A regular polygon is shown, with the measure of one of its angles labeled 3x − 15.

8 sided regular polygon with one angle labeled 3 times x minus 15

Determine the value of x.

x = 40

x = 65

x = 50

x = 135

What is a polygon?polygonis defined as ageometric shapethat iscomposedof 3 or moresidesthese sides are equal in length, and an equal measure of angle at the vertex,For the

octagon,The angle of a vertex is 135°.

Equating the angles,

3x -15 = 135

3x = 135 + 15

3x = 150

x = 50

valueof the x in the givenexpressionis 50°.polygonhere:#SPJ2
