Question

Sec 5a =cosec (a+36) where 5a is the acute angle

Answer 1

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°

Answer 2

Answer:

9°

Step-by-step explanation:

=> cosec(90-5A)=cosec(A+36)

=> 90-5A=A+36

=>90-36=5A+A

=> 54=6A

=> A=9°
