Answer:
x = 94°
Explanation:
The measure of the chord- chord angle CED is half the sum of the arcs intercepted by the angle and its vertical angle, that is
( arc CD + arc AB ) = 82°
Multiply both sides by 2 to clear the fraction
CD + AB = 164°, that is
x + 70 = 164 ( subtract 70 from both sides )_
x = 94°
