Answer:
A. 76
B. 256
Step-by-step explanation:
DF is a diameter so that means the right side of the
circle measure 180 degrees. Angle DGE measures 104, since that the central angle that means Arc DE measures 104 also.
Using arc addition, part of the right side measure 104 so that means the remaining arc must add up to 180.
[tex]104 + x = 180[/tex]
[tex]x = 76[/tex]
Arc EF measure 76.
2. A circle has 360 degrees in it. We are asked to find the measure of the circle expect the Arc ED.
Arc ED measures 104 so
[tex]360 - 104 = 256[/tex]
