Question

find the measure of the arc.

Explanation:

Step1: Determine the measure of the right - angle

A right - angle is \(90^{\circ}\).

Step2: Calculate the measure of arc \(EFD\)

We know that the measure of arc \(EFD\) is the sum of the measure of the \(146^{\circ}\) angle and the \(90^{\circ}\) angle. So, \(m\overarc{EFD}=146^{\circ}+90^{\circ}\).

$$m\overarc{EFD}=236^{\circ}$$

Answer:

\(236\)
