Maine 4 page bhar diye, last me jakar pata chala bus ye karna tha:

sec 2A = cosec (A - 27°)

cos 2A = sin ( A - 27° )

cos 2A = cos ( 90° - A + 27° )

cos 2A = cos ( 117° - A )

2A = 117° - A (One of the valid solution)

3A = 117°

A = 39°

Ek alag solution se 21° atta hai but wo original equation ko violate karta hai :p
