Segment TM is the diameter of circle O.
Segment CU is tangent to circle O at point C.
Secant TU intersects circle O at point S.
CU = 105, SU = 66, SM = 66, and TS = x.
None of the angle measures are given.
3a. Solve for x. Show your work.
3b. what is the measure of angle TSM? Explain how you know.
3c. Based on your answers to 3a and 3b, what is the radius of circle O? Show your work.
