Question

if 2 cos(A+B)=2 sin (A-B)=1; find the values of A and B​

Answer 1

Step-by-step explanation:

2 cos(A+B)=2 sin (A-B)=1

cos(A+B)=1. sin(A-B)=1

A+B=0°. A-B=90°

On solving we get

A=45°

B=-45°

B=180-45=135°

Answer 2

Step-by-step explanation:

2 cos (A+B)=2. sin(A-B)=1

cos (A+B)=1. sin(A-B)=1

A+B=0. A-B=0

A=45°

B=-45°

B=180-45=135°

here is your answer
