Question

8. If sin(A - B) =
cos(A+B) =, 00<A+B=900A>B, find A and B.​

Answer 1

Answer:

a=45

b=15.............

Answer 2

sin(A-B) =½

cos(A+B) =½

and we know that,

sin30°=½

cos60°=½

therefore,

A+B=60 first equation

A-B=30 second equation

adding both the equations we got,

2A=90

A=45

putting value of A in first equation

we get,

B=15

hope it helps
