Answer:
[tex]\Huge \boxed{x=0}[/tex]
Step-by-step explanation:
Angles on a straight line add up to 180 degrees.
y + 50 = 180
y = 180 - 50 = 130
We can use Angle formed by a chord and tangent theorem to solve for x.
The angle formed by a chord and tangent is half the measure of the intercepted arc.
130 = 1/2(2x+260)
Expand brackets.
130 = x+130
Subtract 130 from both sides.
x = 0
