Web5 Jun 2024 · 13. The sum of the interior angles of a regular polygon is 1,260 degrees. Find the area of the polygon if its perimeter is 45 centimeters. Solution. 14. The measure of an interior angle of a regular polygon is 144 degrees. Find the apothem if one side of the polygon measures 5 units. Solution. 15. Web1 Oct 2024 · Since these 5 angles form a perfect circle around the point we selected, we know they sum up to 360°. So, the sum of the interior angles in the simple convex pentagon is 5*180°-360°=900°-360° = 540°. It is easy … WebThe measure of each interior angle of a polygon is 150. Find the number of sides in the polygon Let be the number of sides. Since all angles of a regular polygon are congruent, the sum of the interior angles can be expressed as 150 150 = −2∙180 150 =180 −360 −30 =−360 =12 There are 12 sides. comfortable black flats women
