What is the value of x, in degrees?
to
74°

Answer:
x°= 122°
Step-by-step explanation:
The measure of a chord- chord angle is half the sum of the measures of the arcs intercepted by the angle and its vertical angle, that is
x° = [tex]\frac{1}{2}[/tex] (74 + 170)° = [tex]\frac{1}{2}[/tex] × 244° = 122°
