Question

If the point (x, square root 3/2) is on the unit circle, what is x?

Answer 1

1/2.
You’re welcome

Answer 2

Answer:

$\frac{1}{2}$

Step-by-step explanation:

On a unit circle, the only points where y = $\frac{\sqrt{3} }{2}$ have an x coordinate of $\frac{1}{2}$ or $\frac{-1}{2}$ . Since only one of those is an option, the answer is $\frac{1}{2}$.
