Answer» Answer: SMALLEST angle = 30° Step-by-step explanation: LET the Largest angle be A, smallest be C and other one be B. According to the QUESTION, A=2(B+C) & C=A/4 We KNOW that, A+B+C =180° B+C = 180°-A So, the equations become A= 2(180°-A) ......(I) C= A/4. ...... (II) On solving the (I) one, we get, A= 120° Use it for the (II) equation and we get, C=30°.... Therefore, smallest angle = 30° Hoped it helped all....:-)

10.

largest angle of triangle is twice the sum of other two the sum smallest is 1 by 4 of the largest find the smallest angle

Answer»

Answer: SMALLEST angle = 30°

Step-by-step explanation:

LET the Largest angle be A, smallest be C and other one be B.

According to the QUESTION,

A=2(B+C) &

C=A/4

We KNOW that, A+B+C =180°

B+C = 180°-A

So, the equations become

A= 2(180°-A) ......(I)

C= A/4. ...... (II)

On solving the (I) one, we get, A= 120°

Use it for the (II) equation and we get, C=30°....

Therefore, smallest angle = 30°

Hoped it helped all....:-)

24.	If a + b is equals to 12 and a b is equal to 27 find the value of a cube plus b cube
Answer» Answer: a³ + b³ = 756 Step-by-step explanation: a + b = 12 ------(1) ab = 27 ------(2) from eq. 1 a + b = 12 a = 12 - b PUT a in eq. 2 ab = 27 (12 - b)b = 27 12B - b² = 27 b² - 12b + 27 = 0 b² - 9b - 3b + 27 = 0 b(b - 9)*-3(b - 9) = 0 (b - 9)(b - 3) = 0 b = 9 or b = 3 put b in eq. 1 (if, b = 3) a + b = 12 a + 3 = 12 a = 12 - 3 a = 9 (if, b = 9) a + 9 = 12 a = 12 - 9 a = 3 now, a³ + b³ (if a=3 and b=9) = (3)³ + (9)³ = 27 + 729 = 756 or, if a = 9 and b = 3 then, a³ + b³ = (9)³ + (3)³ = 729 + 27 = 756 so , a³ + b³ = 756

24.

If a + b is equals to 12 and a b is equal to 27 find the value of a cube plus b cube

Answer»

Answer:

a³ + b³ = 756

Step-by-step explanation:

a + b = 12 ------(1)

ab = 27 ------(2)

from eq. 1

a + b = 12

a = 12 - b

PUT a in eq. 2

ab = 27

(12 - b)b = 27

12B - b² = 27

b² - 12b + 27 = 0

b² - 9b - 3b + 27 = 0

b(b - 9)*-3(b - 9) = 0

(b - 9)(b - 3) = 0

b = 9 or b = 3

put b in eq. 1

(if, b = 3) a + b = 12

a + 3 = 12

a = 12 - 3

a = 9

(if, b = 9) a + 9 = 12

a = 12 - 9

a = 3

now, a³ + b³ (if a=3 and b=9)

= (3)³ + (9)³

= 27 + 729

= 756

or, if a = 9 and b = 3

then, a³ + b³

= (9)³ + (3)³

= 729 + 27

= 756

so , a³ + b³ = 756

the value of the expression (10y-20) depends on the value of y verify this by giving five different values to y and finding for each y the value of (10y - 20) . from the different values of (10y- 20) you obtain, do you see a solution to 10y -20 =50? if there is no solution, try giving more values to y and find whether the condition 10y-20=50 is met

Answer»

10Y -20=50

10y =50+20

10y = 70

y = 70/10

y = 7

42.	Use a suitable identity and factorise a. x^2/4 - y^2/4 b. x^2=y^2/100
Answer» ANSWER: a. (x + y)(x - y)/4 and b. (10x + y)(10x - y) = 0 Step-by-step EXPLANATION: a. We know that a² - b² = (a - b)(a + b) So, x²/4 - y²/4 = (x² - y²)/4 = (x + y)(x - y)/4 b. x² = y²/100 x² - y²/100 = 0 a² - b² = (a - b)(a + b) (x)² - (y/10)² = 0 (x + y/10)(x - y/10) = 0 (10x + y)(10x - y)/10 = 0 (10x + y)(10x - y) = 0*10 (10x + y)(10x - y) = 0

Use a suitable identity and factorise a. x^2/4 - y^2/4 b. x^2=y^2/100

Answer»

ANSWER:

a. (x + y)(x - y)/4 and b. (10x + y)(10x - y) = 0

Step-by-step EXPLANATION:

a. We know that

a² - b² = (a - b)(a + b)

So, x²/4 - y²/4 = (x² - y²)/4

= (x + y)(x - y)/4

b. x² = y²/100

x² - y²/100 = 0

a² - b² = (a - b)(a + b)

(x)² - (y/10)² = 0

(x + y/10)(x - y/10) = 0

(10x + y)(10x - y)/10 = 0

(10x + y)(10x - y) = 0*10

(10x + y)(10x - y) = 0

43.	Find the value of a so that the point (3,a), lies on the line represented by 2x+3y=5.
Answer» Step-by-step explanation: those points are on the LINE MEANS if we PUT that point in the equation, it must satisfy the equation. and (x,y),this refers to x co-ordinate and y co-ordinate respectively therefore putting x=3 and y=a in the equation, 2(3)+3(a)=5 3(a)=5-6 a=-1/3

Find the value of a so that the point (3,a), lies on the line represented by 2x+3y=5.

Answer»

Step-by-step explanation:

those points are on the LINE MEANS if we PUT that point in the equation, it must satisfy the equation.

and

(x,y),this refers to x co-ordinate and y co-ordinate

respectively

therefore putting x=3 and y=a in the equation,

2(3)+3(a)=5

3(a)=5-6

a=-1/3
