Answer:
60 degrees
Step-by-step explanation:
EF and DC have lines through them indicating that they are equal in length, telling us that the figure is an isosceles trapezoid. Congruent base angles are a property of isosceles trapezoids, like isosceles triangles. This means that the base angles C and F will have the same measure. The measure of angle F is 60 degrees, therefore the measure of angle C will also be 60 degrees.
