## if an angle ABC was inscribed in a circle and measured 70 degrees, what is the degree measure of arc ABC?

Apr 25, 2018

Arc ABC = 220 degrees

#### Explanation:

Angle ABC is an inscribed angle. What this means is that it is half the measurement of the arc it cuts, which is arc AC.

2m Angle ABC = Arc AC
$2 \cdot 70 = A r c A C = 140$

A circle is 360 degrees, so arc ABC must be 360 - Arc AC
$360 - 140 = 220$
