Question

If Sin (A-B) = 1/2 and Cos(A+B) = 1/2 where
0< A+B <_ 90° find A and B.​

Answer 1

Answer:

please please check in Google lens is the app

Answer 2

Answer:

A=45 B= 15

Explanation:

sin(A-B)= 1/2

sin(A-B)=sin30

A-B=30...............(1)

cos(A+B)=1/2

cos(A+B)=cos60

A+B=60................(2)

from (1)and(2) we get

2A=90

A=45

B= 60-45 ( from (2). )

B=15
