Question

4. If tan A=cot B, prove that A + B = 90°​

Answer 1

Answer:-

tan A= cot B ...........(1)

tan (90°-B)= cot B ............(2)

from eq (1) and (2)

tan A =tan (90°-B)

A=(90°-B)

therefore,

A+B=90°

Hence Proved!!!

Answer 2

hii mate!

Given that tanA=cot B

cot(90°-A) = cot B

tan theeta = cot(90°-theeta)

90°-A= B

A+B= 90°

hope my ans helps u☺️
