WebUsing The Exterior Angle Theorem To Solve Problems. Example: Find the values of x and y in the following triangle. Solution: x + 50° = 92° (sum of opposite interior angles = … WebThis is a result of the interior angles summing to 180(n-2) degrees and each exterior angle being, by definition, supplementary to its interior angle. Take, for example, a triangle with three vertices of 50 degrees, 70 degrees, and 60 degrees. The interior angles sum to 180 degrees, which equals 180(3-2). Because the exterior angles are ...

When looking at … WebSolution: We know that sum of all the interior angle in a polygon = (n - 2) × 180°. Here, n = 29. Therefore, the sum of all interior angles = (29 – 2) × 180°. = 27 × 180°. = 4860°. 2. If the sum of the measure of the interior angle of polygon is … Webunderstand the relationship between interior and exterior angles and their sums in a convex polygon, understand that the sum of the exterior angles of a convex polygon is … basildon minibus hire
