Question

If sinA=½, cosB=½, the (A+B) will be equal to?​

Answer 1

Answer:

Step-by-step explanation:

Given → SinA = 1/2

So, A = 30° ( as sin30 = 1/2)

CosB = 1/2

So, B = 60°. ( as cos 60= 1/2)

→→ A+B = 30+60 = 90°

Answer 2

Answer:

Sin A = 1/2 and Cos B = 1/2

Sin A = Sin 30°

or , A = 30°

Again,

Cos B = 1/2

Cos B = Cos 60°

or , B = 60°

So , A+B

or , 30°+60° = 90°
