Find the measure of arc DF. Circle A with chords EF and CD that intersect at point G, the measure of arc EC is 5x plus 10 degrees, the measure of angle EGC is 70 degrees, and the measure of arc DF is 11x plus 2 degrees. 50° 90° 100° 140°

90 deg

Step-by-step explanation:

The measure of the angle of two intersecting chords is the sum the measures of the arcs divided by 2.

(5x + 10 + 11x + 2)/2 = 70

16x + 12 = 140

16x = 128

x = 8

m(arc)DF = 11x + 2

m(arc)DF = 11(8) + 2

m(arc)DF = 90

it could be a ..idk tho
