Which angle, θ, forms the point on the unit circle with the coordinates (sqrt2/2, sqrt2/2)? 30 45 60 90

Option B.

Step-by-step explanation:

The given point is

Both coordinates are positive, so the point lies in the 1st quadrant.

We need to find the angle, θ, forms the point on the unit circle with the given point.

If a point is (a,b), then

Using this formula we get

On comparing boh sides we get

Therefore, the correct option is B.

the answer is 0.071
