Answers

Answered by ShanAgrawal

tan 2A = cot A - 18
cot (90 - 2A) = cot (A - 18)
so,
90 - 2A = A - 18
3A = 108
so,
A = 36

Tawhid2002: 36

Tan 2A = Cot (A-18)
_______________________________________________________

We know that Tan A = Cot (90-A)

Cot (90-2A) = Cot (A-18)

Cancelling Cot on both sides.

90 - 2A = A - 18

3A = 90 + 18

A = 108/3

A = 36°
