Question

If T is the midpoint of SU what are ST, TU, and SU?

a. ST = 7, TU = 63, and SU = 126


b. ST = 63, TU = 63, and SU = 126


c. ST = 80, TU = 80, and SU = 160


d. ST = 18, TU = 18, and SU = 36

Answer 1

B

Explanation:

As T is the midpoint of SU, ST=TU. 9x=5x+28, 4x=28, x=7. ST=TU=63 and SU=126
