Answer:

x = 58

Step-by-step explanation:

Given an angle outside a circle formed by a tangent and a secant then

angle = [tex]\frac{1}{2}[/tex] difference of the measures of the intercepted arcs, that is

51 = [tex]\frac{1}{2}[/tex] (160 - x) ← multiply both sides by 2

160 - x = 102 ( subtract 160 from both sides )

- x = - 58 ( multiply both sides by - 1 )

x = 58
