The sum of all three angles in a triangle is always 180°. Therefore, to find the measure of the third angle, we need to subtract the sum of the first two angles from 180°.
Third angle = 180° - (39.5° + 61.7°)
Third angle = 180° - 101.2°
Third angle = 78.8°
Therefore, the measure of the third angle is 78.8°.
If a triangle has angles of 39.5°
and 61.7°
, what is the measure of the third angle?(1 point)
