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

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
