Question

If A and B are acute angles such that sin (A + B) = 1 and cos(A - B) = 1
find A and B.​

Answer 1

Answer:

A=B=45

Step-by-step explanation:

sin(A+B) = 1  => A+B = 90    ---------(1)

cos(A-B) = 1 =>  A-B = 0  => A=B --------------------(2)

Using  (1) and (2) , we get

2B =90 => B = 45

SO, A = B = 45
