Answer 2

$\boxed{ANSWER;}$

Given;

• Sec5A=Cosec(A-36)
• And 5A is an acute angle

To Prove;

• A=21

Solution;

• Sec5A=Cosec(A-36)

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

We know that

• Cosec(90 - Ø) = secØ

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

Then,

• Sec5A = cosec(A - 36)

• Cosec(90 - 5A) = cosec(A - 36)

• 90 - 5A = A - 36

• -5A-A= -36-90

• -6A= -126

• A= -126/-6

• A=21
