To determine the third angle of a triangle when two angles are given, we use the fundamental property of triangles: the sum of the interior angles of a triangle is always 180°. Given: - First angle = 50° - Second angle = 30° To find the third angle, we use the formula: \[ \text{Sum of angles in a triangle} = 180° \] \[ \text{Third angle} = 180° - (\text{First angle}…Read More
