Question

find the measure of the arc.
m\overset{\frown}{edf} = ?°

Explanation:

Step1: Use angle sum in a circle

The sum of angles around a point is \(360^{\circ}\).

Step2: Calculate \(m\overarc{EDF}\)

We know one angle is \(90^{\circ}\) (right - angle) and another is \(146^{\circ}\). So \(m\overarc{EDF}=360^{\circ}-(90^{\circ} + 146^{\circ})\).
