Question

what is the measure of ZDEG on circle O?​

Answer 1

Answer:

∠ DEG = 50°

Step-by-step explanation:

Angles on the circle subtended by the same arc are congruent.

∠ CFG and ∠ DEG are angles on the circle subtended by arc CD , then

∠ DEG = ∠ CFG = 50°

Answer 2

Answer:

50° parallel lines subtended on circumference theorem, and congruent angles seen as subtended on same arc lone examples attached.
