Question

If cos (A-B)=1/root 2 sin(A+B) = root 3/2 & A,B are acute angles whose sum is acute find A and B​

Answer 1

Step-by-step explanation:

A-B= 45

A+B=60

2A= 105

A= 105/2

A= 52(1/2)

B= 60-52(1/2)

B=7(1/2)

Answer 2

Answer:

A=52.5, B=7.5

Step-by-step explanation:

cos(A-B)=1/rt2

A-B=45   ...(1)

sin[A+B]=rt3/2

A+B=60    ....(2)

From 1 & 2

A=52.5, B=7.5
