1. ('7 points) Assume 6' is in radians. The angles requested are measured counterclockwise from the positive :raxis to the ray corresponding to the given point and are in [0, 2:7]. The three right triangles depicted with one side on the :raxis all have horizontal sides of the same length. Let 'U = 3 cm. (a) (2 points) W'rite h in terms of 6'. Then write 6' in terms of h. (b) (2 points) Fill in the table below. Answers may include 1)., (9 (but not h]. Justify your work. point coordinate angle A ( , l B ( a J (c) (1 point) If h : 7 cm, what is the radius 7"
