Question

if 15 cot a = b, then find the value of cosec a ​

Answer 1

Answer:

Correct answer is=15+b/15

Step-by-step explanation:

1st step:cot a =b/p(draw a right angled triangle roughly and name it A, b, c)

15 cot a =b,

cot a =b/15

2nd step:As we know that,

cot a=b/p, so, Base=b, Perpendicular=15

3rd step:Now by Pythagoras theorem find out the hypotenuse, H^2 =P^2+B^2

H^=15^2+b^2

H^2=225+b^2

Now do square root on both sides,

H=15+B

4th step:As we know that cosec a=h/p

So, cosec a=15+b/15.

I hope this answer wuold be helpful to you, Thank you.
