Question

Given that sin alpha = root 3 by 2 and cos beta = 0 then the value of beta - alpha is

Answer 1

Answer:

Sin alpha = √3/2

But sin 60° = √3/2

Therefore alpha = 60°

Cos beta = 0

But cos 90° = 0

Therefore beta = 90°

Beta - alpha = 90° - 60° = 30°

Answer 2

Answer:

it will 30 cause if we look at table we got sin60 = root3/2 and cos90 = 0 so we subtract

beta - alpha

90 - 60 = 30

therefore

beta-alpha = 30
