2.	In triangle ABC, right angled at B,AB=15cm,BC=8cm. determine;. 1)sinA,cosA. 2)sinC,cosC
Answer» Given: In triangle ABC, right-angled at B, AB = 15 CM BC = 8 cm To determine: (1) sinA, cosA (2) sinC, COSC Solution: We have to first find the length of the hypotenuse i.e., AC by using the Pythagoras theorem: $AC^2 = AB^2 + BC^2$ $\implies AC = \sqrt{AB^2 + BC^2}$ substituting the AB = 15 cm & BC = 8 cm $\implies AC = \sqrt{15^2 + 8^2}$ $\implies AC = \sqrt{289}$ $\implies AC = 17\:cm$ (1). Finding the value of SIN A and cos A: From the figure attached below, Considering the angle A, we have BC = perpendicular = 8 cm AC = hypotenuse = 17 cm AB = base = 15 cm ∴ $\bold{sin \:A = \frac{perpendicular}{hypotenuse} = \frac{8}{17}}$ and ∴ $\bold{cos\:A = \frac{base}{hypotenuse} = \frac{15}{17}}$ (2). Finding the value of sin C and cos C: From the figure attached below, Considering the angle C, we have BC = base = 8 cm AC = hypotenuse = 17 cm AB = perpendicular = 15 cm ∴ $\bold{sin \:C = \frac{perpendicular}{hypotenuse} = \frac{15}{17}}$ and ∴ $\bold{cos\:C = \frac{base}{hypotenuse} = \frac{8}{17}}$ ------------------------------------------------------------------------------------ Also View: In triangle ABC, right angle at B, if AB = 12 cm and BC = 5 cm, find 1) Sin A and TAN A, 2) Sin C and Cot C. brainly.in/question/2284157 In triangle abc right angled at b ab=7cm and (ac-bc) =1cm.

2.

In triangle ABC, right angled at B,AB=15cm,BC=8cm. determine;. 1)sinA,cosA. 2)sinC,cosC

Answer»

Given:

In triangle ABC, right-angled at B,

AB = 15 CM

BC = 8 cm

To determine:

(1) sinA, cosA

(2) sinC, COSC

Solution:

We have to first find the length of the hypotenuse i.e., AC by using the Pythagoras theorem:

$AC^2 = AB^2 + BC^2$

$\implies AC = \sqrt{AB^2 + BC^2}$

substituting the AB = 15 cm & BC = 8 cm

$\implies AC = \sqrt{15^2 + 8^2}$

$\implies AC = \sqrt{289}$

$\implies AC = 17\:cm$

(1). Finding the value of SIN A and cos A:

From the figure attached below,

Considering the angle A, we have

BC = perpendicular = 8 cm

AC = hypotenuse = 17 cm

AB = base = 15 cm

∴ $\bold{sin \:A = \frac{perpendicular}{hypotenuse} = \frac{8}{17}}$

and

∴ $\bold{cos\:A = \frac{base}{hypotenuse} = \frac{15}{17}}$

(2). Finding the value of sin C and cos C:

From the figure attached below,

Considering the angle C, we have

BC = base = 8 cm

AC = hypotenuse = 17 cm

AB = perpendicular = 15 cm

∴ $\bold{sin \:C = \frac{perpendicular}{hypotenuse} = \frac{15}{17}}$

and

∴ $\bold{cos\:C = \frac{base}{hypotenuse} = \frac{8}{17}}$

Answer» Answer: 34.25 Step-by-step EXPLANATION: let the TOTAL score be Total RUNS in 10 MATCHES = 38.9 * 10 = 389 now we calculate Total runs in first 6 matches = 42 * 6 = 252 now we see that So, total runs in last 4 matches = 389 - 252 = 137 so the score comes as Average for last 4 matches = 137/4 = 34.25

8.

Average score for 10matches is 42 find the average score of last 4 matches is

Answer»

Answer:

34.25

Step-by-step EXPLANATION:

let the TOTAL score be

Total RUNS in 10 MATCHES = 38.9 * 10 = 389

now we calculate

Total runs in first 6 matches = 42 * 6 = 252

now we see that

So, total runs in last 4 matches = 389 - 252 = 137

so the score comes as

Average for last 4 matches = 137/4 = 34.25

13.

∆ ABC, ∠A +∠B = 116° and ∠B + ∠C = 126°. The measure of angles ∠A, ∠B and ∠C are

Answer»

To find :-

we NEED to find measure of angles ∠A, ∠B and ∠C

Solution :

∠A +∠B = 116° .....1)
∠B + ∠C = 126° ......2)

From equation (1)

⠀⠀⠀⠀⠀⠀∠A +∠B = 116

⠀⠀⠀⠀⠀⠀∠B = 116 - ∠A .....3)

From equation (2)

⠀⠀⠀⠀⠀⠀∠B + ∠C = 126°

⠀⠀⠀⠀⠀⠀116 - ∠A + ∠C = 126°

⠀⠀⠀⠀⠀⠀∠C - ∠A = 126 - 116

⠀⠀⠀⠀⠀⠀∠C = 10 + ∠A ....(4)

We know that,

♻️Sum of all angles of triangle = 180

So,

∠A + ∠B + ∠C = 180

From (3) and (4)

⟶ ∠A + (116 - ∠A) + 10 + ∠A = 180

⟶ ∠A + 116 - ∠A + 10 + ∠A = 180

⟶ ∠A + 126 = 180

⟶ ∠A = 180 - 126

⟶ ∠A = 54

So,

⇝∠B = 116 - ∠A

⇝∠B = 116 - 54

⇝∠B = 62

And

›› ∠C = 10 + ∠A

›› ∠C = 10 + 54

›› ∠C = 64

Hence,

Measure of all angles of ∆ABC are :-

∠A = 54
∠B = 62
∠C = 64

Verification :-

Sum of all angles of triangle = 180

››➔ ∠A + ∠B + ∠C = 180

››➔ 54 + 62 + 64 = 180

››➔ 54 + 126 = 180

››➔ 180 = 180

LHS = RHS

Hence VERIFIED.

Answer» LET the ages of A and B be x and y years respectively. Then, x−y=±2 [Given] D's age =2x years and, C's age =y/2 years Clearly, D is older than C 2x− y/2 =40⇒4x−y=80 Thus, we have the FOLLOWING TWO systems of linear equations x−y=2 .(i) and, 4x−y=80 (II) or x−y=−2 (iii) and, 4x−y=80 ..(iv) Substracting equation (i) from equation (ii), we GET 3x=78⇒x=26Putting x=26 in equation (i), we get y=24 or Substracting equation (iv) from equation (iii), we get −3x=−82⇒x=82/3 = 27⅓ Putting x= 82/3 in equation (iii), we get y= 82/3 +2=88/3 =29 ⅓ Hence, A's age =26 years and B's age =24 years or A's age =27 ⅓ years and B's age =29 ⅓ years.

A and B are friends and their agesdiffer by 2 years A's father D is twiceas old as A and B is twice as old as hissister c theageof D and C differ by 40years. find the ages ofA and BA

Answer»

LET the ages of A and B be x and y years respectively. Then,

x−y=±2 [Given]

D's age =2x years and, C's age =y/2 years

Clearly, D is older than C

2x− y/2 =40⇒4x−y=80

Thus, we have the FOLLOWING TWO systems of linear equations

x−y=2 .(i)

and, 4x−y=80 (II)

or

x−y=−2 (iii)

and, 4x−y=80 ..(iv)

Substracting equation (i) from equation (ii), we GET

3x=78⇒x=26Putting x=26 in equation (i), we get y=24

or

Substracting equation (iv) from equation (iii), we get

−3x=−82⇒x=82/3 = 27⅓

Putting x= 82/3 in equation (iii), we get

y= 82/3 +2=88/3 =29 ⅓

Hence, A's age =26 years and B's age =24 years

or

A's age =27 ⅓ years and B's age =29 ⅓ years.

Answer» Step-by-step explanation: 15/(x2 - 4) – 2/(x - 2) = 1. 15/(x2 - 22) – 2/(x - 2) = 1. 15/(x + 2)(x - 2) – 2/(x - 2) = 1. [15 – 2(x + 2)]/[(x + 2)(x - 2)] = 1. [15 – 2X - 4] /[(x + 2)(x - 2)] = 1. [11 - 2x]/[(x + 2)(x - 2)] = 1. 11 – 2x = (x + 2)(x - 2). 11 – 2x = x2 - 4. x2 - 4 = 11 – 2x. x2 + 2x – 4 – 11 = 0. x2 + 2x – 15 = 0. x + 5) (x - 3) = 0. x + 5 = 0 or, x – 3 = 0 x = -5 or, x = 3. Therefore, x = -5 and 3.

If a,b,c do not belong to the set {1,2,3----9} then log 10{a+10b+10^2c/10^-4a+10^-3b+10^-2c

Answer»

Step-by-step explanation:

15/(x2 - 4) – 2/(x - 2) = 1.

15/(x2 - 22) – 2/(x - 2) = 1.

15/(x + 2)(x - 2) – 2/(x - 2) = 1.

[15 – 2(x + 2)]/[(x + 2)(x - 2)] = 1.

[15 – 2X - 4] /[(x + 2)(x - 2)] = 1.

[11 - 2x]/[(x + 2)(x - 2)] = 1.

11 – 2x = (x + 2)(x - 2).

11 – 2x = x2 - 4.

x2 - 4 = 11 – 2x.

x2 + 2x – 4 – 11 = 0.

x2 + 2x – 15 = 0.

x + 5) (x - 3) = 0.

x + 5 = 0 or, x – 3 = 0

x = -5 or, x = 3.

Therefore, x = -5 and 3.

It means that second number will be 2 more than first number, third number will be 4 more than first number and the fourth number will be 6 more than first number. If you subtract 2 from second number, 4 from third number and 6 from fourth number then all the numbers will be equal to one another. If you subtract (2+4+6) or 12 from the SUM of the numbers (27*4) or 108, new sum will be (108–12) = 96 This sum or 96 will be the sum of four equal numbers so first number will be 96/4 or 24 Largest number will be 24+6 = 30

None of theIs the average of the largest and the smallest of fournumbers greater than the average of the fournumbersMT200

Answer»

Answer:

You can SOLVE such types of questions orally if you understood this

The later consecutive even or odd number always will be 2 more than the previous number.

It means that second number will be 2 more than first number, third number will be 4 more than first number and the fourth number will be 6 more than first number.

If you subtract 2 from second number, 4 from third number and 6 from fourth number then all the numbers will be equal to one another.

If you subtract (2+4+6) or 12 from the SUM of the numbers (27*4) or 108, new sum will be (108–12) = 96

This sum or 96 will be the sum of four equal numbers so first number will be 96/4 or 24

Largest number will be 24+6 = 30
