Question

If sin(A-B)=½,cos(A+B)=½,0<A+B<90,A>B then find A, B​

Answer 1

Answer:

The value of A and B is :-

A = 45

B = 15

Answer 2

Answer:

A=45

B=15

Step-by-step explanation:

SIN(A-B)=1/2

OR, SIN(A-B)=SIN30০

SO, A-B=30০.......(1)

SAME WAY,

A+B= 60০.............(2)

NOW 1+2

2A=90০

SO A=45০

NOW PUTTING THE VALUE OF A INTO 1

SO, B= 15০
