How To Calculate The Pentagon’S Fifth Exterior Angle?

The sum of exterior angles of a regular pentagon is equal to 360°, and the formula for calculating each exterior angle is 360°/n = 360°/5 = 72°. Each exterior angle is supplementary to the interior angle, and there are five exterior angles of a pentagon. The total of a regular pentagon’s outside angles equals 360°, so the formula for calculating each exterior angle is 360°/n = 360°/5 = 72°.

For a pentagon with five sides, the fifth angle measures 90°. The sum of the four angles of a convex pentagon is 60°, and the sum of the exterior angles of a polygon is 360∘. Thus, the measure of the fifth exterior angle is 120 degrees if the four of the exterior angles of a regular pentagon measure 60°.

In conclusion, the sum of interior angles of a polygon is 360∘, and the formula for calculating each exterior angle of a regular pentagon is 360°/n = 360°/5 = 72°. The formula for calculating the exterior angles of a regular pentagon is 360°/n, and the formula for finding the sum of interior angles and solving problems involving interior angles and exterior angles is 360∘.
