Question

ART Rachaunn is laying out a pattern for a stained glass window. So far he has placed the 13 regular polygons shown. Find the measure of each angle at the circled vertex. Then find the sum of the angles.​

Answer 1

180 degrees in a triangle so as triangle is equilateral that angle would be 180/3= 60 degrees

360 degrees in a square. 4 angles in a square. 360/4= 90 degrees

720 degrees in a hexagon. 6 angles in a hexagon. 720/6 = 120 degrees

360 degrees around a point.

so the answer is d.
