Question

question 8 of 10
if a point c is inside ∠avb, then m∠avc + ____ = m∠avb.
m ∠avb = 62°
a. m∠avc
b. m∠avb
c. m∠cvb
d. m∠bva

Explanation:

Step1: Recall angle - addition postulate

If a point \(C\) lies in the interior of \(\angle AVB\), then the measure of \(\angle AVB\) is the sum of the measures of \(\angle AVC\) and \(\angle CVB\). That is, \(m\angle AVC + m\angle CVB=m\angle AVB\).

Answer:

C. \(m\angle CVB\)
