Question

If tan A = cot B then prove that A + B = 90

Answer 1

hey mate !

your answer is -:

step by step -:::

to prove -: A + B = 90

proof -:

tan A = Cot B

{ tan A = Cot( 90 - A )}

Cot( 90 - A ) = Cot B

90 - A = B

A+B = 90

Hence proved

hope it's useful to you

Answer 2

concept

tan A= cot (90- A)

solution

tan A = cot B

cot (90-A) = cot B

therefore,

90-A = B

A + B = 90
