Find The Sum Of The Measures Of The Interior Angles Of The Convex Polygon With N=15. Sum of Interior Angles of Polygones. For a 15-sided polygon plug in 15 for n and simplify.
Hence we can say now if a convex polygon has n sides then the sum of its interior angle is given by the following formula. Use the Polygon Interior Angles Sum Theorem to find the sum of its interior angle measures. S n-2 180 15 -2 180 13 180 156 n 15 15 Exercises.
Substitute n 18 in.
So n 180-E n150 12150 1800 is another way to get the answer. Hence we can say now if a convex polygon has n sides then the sum of its interior angle is given by the following formula. 4x 7 19checking. Use the Polygon Interior Angles Sum Theorem to find the sum of its interior angle measures.
