Question

What is the measure of arc DF?

Answer 1

Posted earlier but got the wrong answer because I did 38*2 which is not correct since E is not the center point.

Answer 2

if you find the measurement for angle O it will also be the measurement for arc DF

Answer 3

Is that equation still correct even though it isnt the center point?

Answer 4

How can I solve for O?

Answer 5

If it's the center, the arc has the same measure of the angle. If it's an inscribed angle, then the arc is twice the angle.

Answer 6

Angle O has the same measure are the arc it intercepts.
