Question

If tanA=cotB,then prove that angle(a+b)=90°

Answer 1

Answer:

This is the answer-------

Step-by-step explanation:

Given: tanA= cotB

To prove: (a+b)= 90°

Proof-

tanA= cotB

tanA= tan(90°-B). [ cotB= tan(90°-B)]

A= 90°-B.

[By eliminating tan from both sides]

Hence, A+B= 90° Proved
