A certain polygon has sides; each side has a length of 7 inches. Each interior angle in the polygon measures 162°. What is the perimeter of the polygon?A)98 inchesB)119 inchesC)128 inchesD)140 inches Loading... Page navigation ← Daily PWN 079 Daily PWN 081 →
Who can remember that formula ::slices on a weird pizza pie
if each angle is 162 then to bisect that and extending it to the center of the polygon gives us 81 degrees
so 162 -180 gives us the angle at the center for each slice of the pie or 18degrees.
now divide 360 by 18 gives you 20
20 x 7 inches (crust length for each slice) = 140 answer d
