Answered by Paritshith

Answer:

Step-by-step explanation:

we are given that tanA = cotB

tanA = tan(90–B) ( cotB = tan(90–B)

Cancel tan on both the sides so

A = 90–B

A+B = 90

Hence proved.

Hope this answer helps you

Paritshith: No check it twice

Answered by Lalablackmama

Step-by-step explanation: tan (-A)= cot B

tan(-A)=tan(90-B)

Therefore -A=90-B

Therefore -A+B=90.
