(not degrees)
Question options:

+37153 Since the lines are all the same length, the angles are all the same measure. The three angles equally divide the entire 360 degree circle. 1/3 of 360 degrees is 120 degrees.

The circumference of a circle is given by pi d where diameter = 2r = 24
115 degrees is a fraction of the 360 degrees of a complete circle.....this fraction is 115/360 ...so the arc length will be
(115/360) * pi * 24 = 24.07 inches
