Four points are plotted on the circumference of a circle and are joined by line segments.

If arc mFG=60
degrees, then what is the measure of ∠FDG
?

(1 point)
degrees

The measure of an angle at the center of a circle is twice the measure of the corresponding arc. Therefore, if arc mFG is 60 degrees, then angle FDG is 2 * 60 = 120 degrees.
