Question

Ifsin (A-B)=1/2.Cos (A + B) = , where 0° <A+B=90° andA>B, find Aand B.​

Answer 1

Answer:

Step-by-step explanation:

sin(A-B) =1/2

sin(A-B) =sin 30       (bcause 1/2=30)

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

cos(A+B) = 1/2

cos (A+B) =cos 60

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

Adding 1 and 2 we get 2A = 90

A = 90/2

A= 45

substituting A=45 in 1

A-B = 30

45-B=30

-B=30-45

-B=-15

B=15
