Question

If tanA=cotB where A and B are acute angles prove that A+B=90

Answer 1

tanA= tan(90-B)
A=90-B
A+B=90
Proved

Answer 2

hi frnd your amswer is as follows..

tanA = cotB .............(given)
cot(90 - A) = cotB. ..............(by putting formula
of tan A= cot( 90-A) )

cancel cot on both side,we get..

90-A = B
90= A+B

hence prove..
