Question

Given that sin A = ½ and cais B =½
then find the value of (A+B)
a)o°
b) 30°
c)60
d)90°​

Answer 1

Answer:

d) 90

Step-by-step explanation:

Sin A = 1/2

Sin A = Sin 30

A = 30

now,

Cos B = 1/2

Cos B = Cos 60

B = 60

therefore, the value of (A+B) :-

(A+B) = ( 30 + 60 )

(A+B) = 90

Answer 2

Answer:

d) 90°

Step-by-step explanation:

sin A = 1/2 =30°

cos B =1/2 = 60°

30° +60° = 90°
