The interior angle of a regular polvgon is 9 times the size of its exterior angle
Thepotemich [5.8K]
<h3>Answer:   20 sides</h3>

==================================================

Work Shown:

x = exterior angle

9x = interior angle

interior + exterior = 180

9x+x = 180

10x = 180

x = 180/10

x = 18

n = number of sides

n = 360/x

n = 360/18

n = 20

There are <u>20</u> sides to the regular polygon.

Side notes:

  • The formula to determine n only works for regular polygons.
  • A polygon with 20 sides is known as an icosagon.
  • Any pair of adjacent interior and exterior angles are supplementary. They add to 180 degrees.

Step-by-step explanation:

<u>Step 1: Set up</u>

75 + 120 + 90 + ∠4 = 360

<u>Step 2: Solve</u>

  1. Add:                                                                                                                   285 + ∠4 = 360
  2. [Subtraction Property of Equality] Subtract 285 on both sides:                   ∠4 = 75
