Atriangle has angles measuring 43.5 and 62.8
1. what is the measure of the triangle's third angle?
2. classify the triangle by sides and angles

All 3 angles of a triangle measure 180 degrees.

43.5 + 62.8 = 106.3

180 - 106.3 = 73.7

So the third angle is 73.7.

This is an acute triangle because all 3 angles of the triangle are less than 90 degrees.

This is a scalene triangle because all 3 angles are different.
