Answer 1

Step-by-step explanation:

Given,

sin(A+B) = 1

cos(A-B) = root3/2

Solution,

Sin (A+B)=1

Sin 90 degree=1

So,A+B= 90 --------i

NOW,

COS(A-B) = ROOT3/2

COS 30= ROOT3/2

SO,A-B = 30--------ii

So,

A+B=90

A-B=30

ADD EQN.1 AND 2,

2A=120

A= 120/2

A=60

NOW,

B=90-60

B= 30

THEREFORE, A= 60 AND B = 30

ANS............

B= 60
