Answer 7

Central Angle DOE has measure 28 degrees.

The measure of the central angle of a circle is the same as its intercepted arc .

That makes Arc DE = 28 degrees. It is a minor arc because its measure is less than 180 degrees.

Answer 8

That leaves a major arc to find.
@TylerMckinney16

Add these numbers: 57 + 95 + 28 + 57 = ?

Answer 13

Yes.

The two angles marked in red are vertical angles and are congruent.


As you have calculated the major arc has measure 237 degrees.

There are several ways to name the arc.

You need the beginning point, the end point, with a point on the arc between them.

Major Arc BDA will measure 237 degrees will do.
