Answer:
The measure of arc EF = 146°
Step-by-step explanation:
From the figure we can see two circles with same center.
From the figure itself we get measure of arc AB is same as measure of arc EF, measure of arc Ac is same as measure of arc ED and measure of arc BC is same as arc FD.
The measure of arc AB = 146°
Therefore the measure of arc EF = 146°
