The sum of the angles of a triangle is always 180 degrees. In this case, we can find the measure of the third angle by subtracting the measures of the given angles from 180 degrees.
Third angle = 180 - 39.5 - 61.7
Third angle = 180 - 101.2
Third angle = 78.8 degrees
Therefore, the measure of the third angle in the triangle is 78.8°.
If a triangle has angles of 39.5°
and 61.7°
, what is the measure of the third angle?(
