Question

If sinθ = 1 2 and 0° < θ < 90°, then cos 2θ

Answer 1

Answer:

1/2

Step-by-step explanation:

sinθ = 1/2

So θ = 30°

So, cos2θ = cos60° = 1/2

Answer 2

Step-by-step explanation:

sin theta=1/2 means theta=30 because sin30=1/2.

2 theta=2(30)=60

cos 2theta=cos 60=1/2

THEREFORE YOUR ANSWER IS 1/2 .

I hope you are satisfied by my answer.
