Find The Measure Of An Exterior Angle Of A Triangle. Clearly the exterior angle ACDand the adjacent interior angle ACBare supplementary. New questions in Mathematics.
Looking for something else. An exterior angle of a triangleis formed when any side is extended outwards. If the measure of the exterior angle is 3x - 10 degrees and the measure of the two remote interior angles are 25 degrees and x 15 degrees find x.
The Exterior Angle Theorem states that.
The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles. A triangle has 3 internal angles which always sum. Find the values of x and y in the following triangle. Interactive Demonstration of Remote and Exterior Angles.
