1. RS and ST are tangent lines. Find the value of x.
R
9x - 30
c.
S
3x
T

Answer 1

The Answer is for this is:
x = 15

Answer 2

x = 15

Explanation:

9x-30 = 3x (tangent lines are congruent)

- move the variables to one side

9x-3x=30

6x=30

x=5

--------------

9(5)-30=3(15)

45-30=15

15=15

Done!
