Answer:

  • The value of x is 125°.

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

We see the exterior angle measures given with one unknown.

Recall the sum all exterior angles of a polygon is 360°.

Set up equation and find the unknown value:

  • 70 + 65 + 60 + 40 + x = 360
  • 235 + x = 360
  • x = 360 - 235
  • x = 125
