Calculate the
interior angle of
a 20-sided
polygon (an
icosagon)

162°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 20, thus

sum = 180° × 18 = 3240°, thus

1 interior angle = = 162°

Step-by-step explanation:

The formula for finding the interior angle of a polygon is given as :

where n is the number of sides

substituting the value of n , we have

which will be 18 x 180

therefore, the interior angle of a 20-sided polygon is

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75

d.) yes, because the volume of the cone is greater than the volume of the sphere
