Additional Problems
Problems 1-5 use the following figure:
1. If θ=42° and U=8, find T.
2. If
α=25° and U=16, find S+T.
3. If R=10 and S=8, find the degree measure of
α.
4. If S=2, R=3.5, and U=4.8, find T.
5. Is it possible for the distance between points C and D to be 4 if S=2
and R=3.5? Explain why or why not.
6. A farmer wants to put a fence around the perimeter of a flat field that is in
the shape of a right triangle. One angle of the triangle is 42° and the length
of the side opposite this angle is 60 meters. Find the length of fencing that is
