Question

If A and B are acute angles and SinA = CosB then find the value of A+B

Answer 1

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

           Sin A = sin(90 - B)

            A = 90 - B

            A + B = 90.


Hope this helps!

Answer 2

Answer:

Value of A+B=90°

Explanation:

Given A and B are acute angles.

and

SinA = CosB

=> Sin A = Sin(90-B)

=> A = 90°-B

=> A+B = 90°

Therefore,

Value of (A+B) = 90°
