Question

If A and B are acute angles and sim A = cos B, then find the value of A + B

Answer 1

Answer :-


______________________

Given ,

A and B are acute angles.

sinA = cosB

To find ,

A + B

Salutation ,

sinA = cosB

sinA = sin ( 90° - B )

A = 90° - B

A + B = 90°

______________________

The answer is 90°

Thanks!

Answer 2

Given, Sin A = Cos B, it can be written as

           Sin A = sin(90 - B)

            A = 90 - B

            A + B = 90.


Hope this helps!
