Answer:
x = 70 , x = 24
Explanation:
the measure of a secant- tangent and a tangent- tangent angle is half the difference of the measures of the intercepted arcs.

24 =
(118 - x) ← multiply both sides by 2 to clear the fraction
48 = 118 - x ( subtract 118 from both sides )
- 70 = - x ( multiply both sides by - 1 ) , then
x = 70
10
61 =
(10x + 1 - (5x - 1) ) ← multiply both sides by 2 to clear the fraction
122 = 10x + 1 - 5x + 1
122 = 5x + 2 ( subtract 2 from both sides )
120 = 5x ( divide both sides by 5 )
24 = x
