Question

1. If sec 2A = cosec(A - 36°), find A.
​

Answer 1

Answer:

Step-by-step explanation:

Question: if sec2A = cosec(A-36°), find A. Answer: sec 2A = cosec (A - 36). cosec (90 - 2A) = cosec (A - 36). 90 - 2A = A - 36. 90 + 36 = 3A. 126 = ...

Answer 2

Sec= cosec(90°-A)

So,

sec2A=cosec(90°-2A)

A.T.Q

cosec(90°-2A)=cosec(A-36°)

90°+36°=A+2A

126=3A

A=126/3

A= 42
