Find the Angle on Unit Circle

A ____ angle is an angle whose vertex is a the center of a circle.

What is the value of θ, theta, in degrees on the unit circle?

What is this angle in radians?

Let θ represent an angle on the unit circle, with $$0\le\theta\le\frac{\pi}{2}$$ , such that $$\tan\theta=\frac{\sqrt[]{3}}{3}$$ . Drag and drop the correct answer into each blank. $$\sin\left(3\theta\right)=$$ ​ (a)   $$\cos\left(-4\theta\right)=$$ ​ (b)
