Find the measure of arc ec.
circle a with chords ef and cd that intersect at point g, the measure of arc ec is 5x degrees, the measure of angle egc is 7x degrees, and the measure of arc df is 90 degrees.
50°
70°
100°
140°

answer:   a) 50°

step-by-step explanation:

since the intersection is inside the circle, we add the arcs:

5x + 90° = 14x

        90° = 9x

        10° = x

arc ec = 5x

          = 5(10°)

          = 50°
