Question

if sin(A-B) =1/2 cos (A+B) =1/2 0<A+B<90A>B the fond A, B​

Answer 1

Answer:

A=45 and B=15

Step-by-step explanation:

sin(A-B)=1/2

sin(A-B)=sin 30

A-B=30...........eq1

cos (A+B)=1/2

cos(A+B)=cos60

A+B=60...........eq2

adding eq1 and eq2,we get

2A=90

A=45

45+B=60

B=15

Hope it helps.........
