POLYGONS 1


The total interior angles of the regular polygon is 145800. Find the number of sides.

Solution

Total angles = (n - 2)1800

145800 = (n - 2)1800

81145800 = (n - 2)180 dividing by 1800 both sides.
    1800             1800

81 = n - 2

81 + 2 = n

n = 83

Hence number of sides is 83

TRY THIS……………………….


The total interior angles of the regular polygon is 111600. Find the number of sides.
