Calculate the missing interior angle x
WebThe measure of each interior angle of a regular n-gon is. 1/n ⋅ (n - 2) ⋅ 180°. or. [ (n - 2) ⋅ 180°]/n. The sum of the measures of the exterior angles of a convex polygon, one angle at each vertex is. 360°. The measure of each exterior angle of a regular n-gon is. 360°/n. Note : WebWe know that each exterior angle is supplementary to the interior angle. Thus, from the above formula, we can derive each exterior angle = [180°n -180°n + 360°]/n = 360°/n. Therefore, the sum of exterior angles of a polygon = n (360°/n). As, the number of sides in a pentagon is 5, n=5. Thus, the sum of exterior angles of a pentagon = 5 ...

WebEither way, this angle and this angle are going to be congruent. So we've established that we have two triangles and two of the corresponding angles are the same. And that by itself is enough to establish similarity. We actually could show that this angle and this angle are also congruent by alternate interior angles, but we don't have to.
