A) -221

B) -28

C) -23

D) 4

4) Euclid (circa 330 BC) would have been shocked to learn that it is possible to find the sine of a 480° angle, as right triangle trigonometry gives no values for angles larger than 90°.In fact, though, using the unit circle, it is possible to find sin480° by using the

 opposite/hypotenuse

ratio of a ________ angle.

A) 20°

B) 30°

C) 45°

D) 60°

5) if the arc length of a sector in the unit circle is 4.2, what is the measure of the angle of the sector?
