Question

find the measure of the arc. medf = ?°

Explanation:

Step1: Recall arc - measure property

The measure of an arc is equal to the measure of its central angle.

Step2: Identify central angle for arc EDF

The central angle corresponding to arc EDF is the sum of the right - angle (90°) and the 146° angle.
\[90^{\circ}+ 146^{\circ}\]

Step3: Calculate the sum

\[90 + 146=236^{\circ}\]

Answer:

236
