Question

if sec 5A= cosec (A+36°)​

Answer 1

hii dear..

here is ur answer

Sec5A = cosec(A - 36)

------------

We know,

Cosec(90 - ∅) = sec∅

--------------

Then,

Sec5A = cosec(A - 36)

Cosec(90 - 5A) = cosec(A - 36)

90 - 5A = A - 36

90 + 36 = A + 5A

126 = 6A

126/6 = A

21 = A

==================

Value of A = 21°

I hope this will help you

sec90-theta=cosec theta

therefore..5a=90-theta

and. a+36=theta.

let me suppose theta be X

then,90-5a=x

a+36=x

then...90-5a=a+36

54=6a

then ,a=54/6=9
