Question

1.a)what is the sum of all angles of a polygon with 20 sides?

b)if it is a regular polygon ,what will be each of its angles?

c)the sum of all angles of a polygon us 2700° ,find tge number of sides.

d)why it is not possible that the sum of all angles be 2600°?​

Answer 1

Answer:

a) An icosagon or 20-gon is a twenty-sided polygon.

The sum of any icosagon's interior angles is 3240 degrees.

b) 90 Degree

c) s = (n-2) × 180

where: s = the sum of the interior angles.

n = the number of sides of the polygon.

2700 = 180n – 360

180n = 2700 + 360 = 3060

n = 3060 ÷ 180 = 17.

The polygon has 17 sides.
