Cot 2A=tan(A-36)
=> Tan(90-2A)=tan(A-36)
=> 90-2A=A-36
=> 90+36=A+2A
=> 126= 3A
Therefore, A=42
Hope it helped you

- HERE IS YOUR ANSWER.
If cot2A =tan (A-36)
Find A.
Sol..
Cot 2A =tan(A-36)
We know
Cot (90-2A)=tan (A-36) [cot (90-A)=tanA]
tan(90-2A)=tan(A-36)
90-2A=A-36
90+36= A+2A
126 = 3A
Or
3A = 126
A= 126/3
A= 42
Hence the value of A is =42
