Describing Angles

Describing Angles 1.13 - Solution

arrow_back Return to Describing Angles

The three angles together form a straight angle. Thus, the sum of their measures is 180.180^\circ.

mv+108+mv=180m\angle v+108^\circ+m\angle v=180^\circ
mv+mv=72m\angle v+m\angle v=72^\circ
2mv=722\cdot m\angle v=72^\circ
mv=36m\angle v=36^\circ
Thus, v\angle v has the measure 36.36^\circ.
