Question

Given that sin A=1/2,cosB=1/2then the value of (A+B)is:

Answer 1

Answer:

Sin30=1/2 so,A=30

Cos60=1/2 so,B=60

Then,

(A+B)=(30+60)

=90

Step-by-step explanation:

Answer 2

Answer:

the sum of (A+B) is 90°

Step-by-step explanation:

sin A = 1/2 = sin 30°

cos B = 1/2 = cos 60°

so,A= 30° and B=60°
