Step-by-step explanation:

Proved that A+B =90°

Step-by-step explanation:

It is given to us that Sin A =Cos B.

In that case, we have to prove that A+B =90°

Now, given expression, Sin A = Cos B

Sin A Sin (90-B)

Since, we know that Sin (n*90 - a) = Cos a, if

n=1

Sin a, if n-2

-Cos a, if n=3

and

-Sin a, if n=4

Hence, cancelling Sin from both sides, A=

90°- B, »AtB = 90° (Proved)
