\text { 1. ( } 15 \text { points) For this exercise, consider the angle } \alpha=\frac{8 \pi}{3} \text { . } (a) (1 point) Is this an acute angle,

a right angle, an obtuse angle, a straight angle, or none of these?Explain how you can tell. (b) (2 points) Convert the angle in degree measure. (c) (4 points) Find the length s of the arc, and the area A of the circle sector spanned by a on the circle centered at the origin and of radius r = 6. (d) (2 points) Find two co-terminal angles to a, one being positive, and the other being negative. (e) (3 points) Find a point P on the terminal side of a in standard position. The point should not be the origin. (f) (3 points) Find a point Q on the terminal side of the angle B = 2 n – a. The point should not be the origin.
