The Triangle Angle Sum Theorem states that the sum of the interior angles of a triangle is always 180°.
Given that two angles in the triangle measure 40° and 65°, we can find the measure of the third angle by subtracting the sum of the known angles from 180°.
180° - (40° + 65°) = 180° - 105° = 75°
Therefore, the measure of the third angle in the triangle is 75°.
A triangle has two angles measuring 40° and 65° . Use the Triangle Angle Sum Theorem to find the measure of the third angle.
