Question

If Sin(A-B)=1/2 And Cos(A+B)=1/2 find the value of A And B​

Answer 1

Answer:

A =45⁰ and B = 15⁰

Step-by-step explanation:

sin 30⁰ = 1/2

cos 60⁰ = 1/2

so ,

a-b = 30⁰

a+b = 60⁰

after solving

we get A =45⁰ and B = 15⁰

Answer 2

Answer:

A= 45° and B= 15°

Step-by-step explanation:

sin30° = 1/2

cos 60° =1/2

so,

a-b=30°

a+b=60°

=> A=45°

and B=15°
