Question

Find A and B, if sin(A+B) = 1 and cos(A-B) = 1, where A and B are two acute angles.​

Answer 1

Answer:

Find A and B, if sin(A+B) = 1 and cos(A-B) = 1, where A and B are two acute angles.​

Step-by-step explanation:

sin(A+B) = 1  gives  

A+B=pi/2

cos(A-B) = 1  this means  A-B=0

A=B

Hence A=B=pi/4
