Question

What is the measure of the arc labeled ?

Answer 1

? = 130°

Explanation:

Minor arc VT is labeled ?. Let's call its measure x.

The measure of major arc VT is 360 - x

m<U = [(measure of major arc VT) - (measure minor arc VT))/2

50 = [(360 - x) - (x)]/2

50 = [360 - x - x]/2

100 = 360 - 2x

-2x = -260

x = 130

Answer: ? = 130°

Answer 2

The measure of the arc label is equal to the measure of the central angle that intercepts the arc.
