Question

What are the coordinates of the terminal point for 0=330

Answer 1

Answer: Option C.

Explanation:

The coordinates (x,y) of a terminal point for an angle θ are:

x = cos(θ) and y = sin(θ).

In this case, we have θ = 330°.

Then we have:

x = cos(330°) = 0.866 = (√3)/2

y = sin(330°) = -0.5 = -1/2

then the coordinates of the terminal point are ((√3)/2, -1/2)

Then the correct option is c.
