Question

The measures of the exterior angles of a pentagon are c, 2x, 4x, 5x, and 8x, solve for x

Answer 1

Answer:

X = 18

Step-by-step explanation:

x + 2x + 4x + 5x + 8x =360

20x = 360

20x/20= 360/20

x=18

Answer 2

The value of x in the pentagon angles is 3.6

What are pentagon?

Pentagon are polygons with five sides.

The exterior sides of the pentagon are given as follows:

• x
• 2x°
• 4x°
• 5x°
• 8x°

Exterior angles formula for polygon is as follows:

• exterior angle = 360 / n

where

n = number of sides

Therefore,

x + 2x + 4x + 5x + 8x = 360 / 5

x + 2x + 4x + 5x + 8x = 72

20x = 72

x = 72 / 20

x = 3.6
