-- A scalene triangle has three interior angles and three exterior angles. -- The sum of the interior angles is 180 degrees, and no two of them are equal. -- The sum of the exterior angles is also 180 degrees, and no two of them are equal. -- The sum of each interior angle and its adjacent exterior angle is 180 degrees.
The three angle sum of ANY triangle is 180 degrees.
If it is a scalene triangle then: 180 - the sum of the 2 known angles = x angle
180 degrees
How: The sum of the 3 interior angles of any triangle add up to 180 degrees
