The answer is GIVEN below :

Trigonometry is the study of angles and its ratios. This study prescribes the RELATION amongst the sides of a triangle and angles of the triangle.

There are sine, cosine, tangent, cot, sectant and cosec ratios to an angle of a triangle.

Let me tell you an interesting fact about Trigonometry.

"Triangle" > "Trigonometry"

Remember some formulae now :

sin²θ + cos²θ = 1

sec²θ - tan²θ = 1

cosec²θ - cot²θ = 1

Want to learn more!

Here it is :

sin(A + B) = sinA cosB + cosA sinB

sin(A - B) = sinA cosB - cosA sinB

COS(A + B) = cosA cosB - sinA sinB

cos(A - B) = cosA cosB + sinA sinB

SOLUTION :

Now, cos(5π/3) × cos(37π/6)

= cos[(5 × 180)/3]° × cos[(37 × 180)/3]°

= cos300° × cos2220°

= cos(360° - 60°) × cos{(360° × 6) + 60°}

= cos60° × cos60°,

since cos(2nπ ± θ) = cosθ, where n = 1, 2, 3, ...

= ½ × ½, since cos60° = ½

= ¼

multiply first by 2and second by 5 we get,
10x+16y=18
10x+15y=20
y=-2 put in equation ONE
5x+8(-2)=9
5x+-16=9
5x=25

yes it is composite number

When X =y

Properties of triangles are :-
EQUILATERAL TRIANGLE
1. three angles should be EQUAL with MEASURE of 60 degreee.

2. three sides should be equal
3.three lines of symetry

ISOCELES TRIANGLE
1. two sides are equal.
2.two angles are equal
3. one LINE os symetry

SCALENE TRIANE
1. no sides are equal.
2. no angles are equal
3. no line os symmetry.

A triangle CONTAINS 3 straight line ,3 angles and 3 corners

Sum of all three angles is 180 degreee.



hope it helps uuuu.....

∆ has 3 sides
∆ has 3 ANGLES
∆ 's all 3 angles SUMS is 180°

Let F(X) = 2 √(1-x)

f'(x) = d/dx [ 2 √(1-x) ]

= 2 d/dx ( √1-x) * d/dx(1-x)

= 2* 1/2 * 1/√(1-x) * -1

Hello friend..!!

according to the question we should show the FUNCTION, 1 / x is ONE - one and onto.

1) to prove it is one - one :

let. f( x1 ) = f(x2)

implies, 1 / x1 = 1 / x2

implies, x2 = x1 --------------( 1. )

implies, x1. = x2

therefore, f ( x) is one - one function.

2) to prove it is an onto function :

let, y = 1 / x

implies, x = 1 / y

for all y € R, there exist at least one X in R such that,

f( x) = f ( 1 / y)

= 1 / ( 1/y)

= y.

therefore f( x) is onto function.

[I already SOLVED 3 no. problem in your previous question. So, I am solving the 4th one only.]

The answer is given below :

Given,

a = 3 - √n, where n is a NATURAL number,
n = 1, 2, 3, ...

To find the least positive value of 'a', we need to put n = 2, so that 'a' BECOMES the least.

When n = 2,

a = 3 - √2

So, the least value of 'a' being 'p', p = 3 - √2

Now,

p = 3 - √2

= 2 - √2 + 1

= (√2)² - (2 × √2 × 1) + (1)²

= (√2 - 1)²

Since, p is positive,

√p = √2 - 1

and

1/√p = 1/(√2 - 1)

= (√2 + 1)/{(√2 - 1)(√2 + 1)},
by rationalising the denominator by multiplying both the NUMERATOR and the denominator by (√2 + 1)

= (√2 + 1), since (√2 - 1)(√2 + 1) = 2 - 1 = 1

Now,

√p + 1/√p

= √2 - 1 + √2 + 1

= 2√2

So, option (1) is correct.

Thank you for your question.

Hello user!!!!
The types of triangles based on sides are:
1) EQUILATERAL triangle: this type of triangle has all the sides of EQUAL length.
2) Isosceles triangle: this type of triangle has only TWO sides of equal length.
3) Scalene triangle: this type of triangle has all the sides of different lengths.

The types of triangles based on angles are:
1) RIGHT angled triangle: 90 degrees
2) obtuse angled triangle: more than 90degrees
3)ACUTE angled triangle:less than 90 degrees
4) straight angled triangle: 180 degrees

16x+4x=14+10
20x=24

I THINK this was a CORRECT MATH

Let TIME TAKEN be x
men HOURS days
14 4 18
12 8 x
for ur understanding dont write it in ur notebook( u have to solve it by arrow method but by texting arrow cant be given so apply arrow as instructed- men UPWARD means from 12 to 14..hours DOWNWARD means4 to 8...days downward means 18 to X..)

Now,12/14=4/8×18/X
=12/14=36/4x
4X×12=36×14
X=36×14/48
=21/2
= 10 and half days

I GAVE you the solution paper and see if your doubt MAY GET CLEAR.

HOPE it HELP you

The answer is given below :

Since, the number is divisible by 11 and 91, to find the number, we need to find the lcm of 11 and 91.

Now, 91 = 1 × 7 × 13 and 11 = 1 × 11

So, the lcm of 11 and 91

= 1 × 7 × 13 × 11

= 1001

So, the smallest such number is = 1001.

Thus, the SUM of the DIGITS of the number 1001 is

= 1 + 0 + 0 + 1

= 2

783/3 is answer
783/3=261

Log28=1 because 28^1=28
28.

See the question... it tells U it INCREASES 10 cm per month. For 1 year multiply the given value by 12. Now 10*12=120cm. Now in 5 years you have to multiply it by 5 as it is now converted into uears FORMAT. 120*5=600cm.

You know that 600cm =6m?
Therefore the HEIGHT will be 16 m

I THINK ANSWER MAY be Three digit number

Let the 3 consecutive even integers be (X-2),x,(x+2)
Given:
(x-2)+x+(x-2)=312
3x=312
x=104

so the 3 consecutive even numbers are (x-2)=102,
x=104,
(x+2)=106

Let ram's marks be X and shyam's marks be y.
b/p
x=y+24
or,x-y=24........eq1
Again,
x=65% of x+ y
or,x=65/100×x+y
or,x=13x+13y/20
or,20x=13x+13y
or,7x=13y
or,7x-13y=0........eq2
eq×13-eq2
13x-13y=312
7x-13y=0
(-) (+). (-)
-------------------
6X. = 312
or,x=52
By PUTTING VALUE of x in eq1,
52-y=24
or,y=52-24=28
Therefore, ram got 52 marks and shyam got 28 marks.

Qotient is 41 and REMAINDER is 0

Count the total number of ways or paths that EXIST between two vertices in a directed GRAPH. These paths doesn’t contain a cycle, the SIMPLE enough reason is that a cylce contain infinite number of paths and hence they create PROBLEM.
