Answer 2

Hello......

=> Given ,

=> TanA = CotA

=> Firstly, We know that , by complementary angels ( the sum of two angels is knowns as Complementary )

=> so, Cot(90- thetha) = Tan thetha

=> TanA = Tan(90 - B )

=> Both sides have TanA, so it is cancelled , then the remains A= 90-B

=> So finally we get , A + B = 90
