Question

tanA=cotB to siddh kijiye ki a+b=90°​

Answer 1

Step-by-step explanation:

Given:-

Tan A= Cot B

To prove:-

A+B=90°

Solution:-

Given equation is TanA= Cot B

=>Tan A=Cot B

we know that Tan(90°-B)=Cot B

=>Tan A=Tan (90°-B)

=>A=90°-B

=>A+B=90°

Hence , Proved.

Answer:-

If Tan A= Cot B then A+B=90°

Used formula:-

• TanA=Cot (90°-A)
• CotA=Tan(90°-A)
