Challenge 3: The CUSTOMer is always right! (10 points in total)

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.
N.B.: Diagram is not to scale!

Answer:
3c. Based on your answers to 3a and 3b, what is the radius of circle O? Show your work. (3 points)

Answer 1

Answer:

Step-by-step explanation:

As TM is a diameter

so ∠TSM=90°( angle in semi circle)
