HELP

36) Find the value of x. Assume that lines which appear to be tangent to the circle are tangent.
A) 3
B) 4
C) 5
D) 6

Answer 1

Explanation:

is "12x + 2" supposed to be the arc angle of UW ?

I assume so.

then per tangent secant angle theorem

6x + 4 = (154 - (12x + 2))/2 = (154 - 12x - 2)/2 = 77 - 6x - 1

12x + 4 = 77 - 1

12x = 72

x = 6

so, D is correct.
