Question

if sec 5A=cosec(A-36),where 5A is an acute angle, find the value of A

Answer 1

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°
