Question

if sin(A-B) = 1/2 and 0°<A+B< 90° andCos (A+B) = 1/2 so value for A and B ?​

Answer 1

Answer:

Step-by-step explanation:

Sin (A-B) = 1/2

Sin ( A- B) = Sin 30

A - B = 30 --------- Eq 1

Cos (A + B)= 1/2

Cos (A+B )= Cos 60

A+B = 60 -------- Eq 2

Add Eq 1 and Eq 2

2A = 90

A= 45

Put in Eq 2 we get

B = 15

So answers are A= 45 and B= 15
