The diagram shows a regular hexagon and a regular pentagon.
drek231 [11]

Since a regular polygon has equal interior angles, then the measure of the angle marked x is: 132°.

<h3>What is a Regular Polygon?</h3>

A regular polygon is any n-sided polygon that has equal interior angles and equal sides.

Thus:

  • Each angle of a regular hexagon = 120°
  • Each angle of a regular pentagon = 108°

Therefore:

x = 360 - 120 - 108

x = 132°

Thus, since a regular polygon has equal interior angles, then the measure of the angle marked x is: 132°.
