Question

Find the value of x in the given diagram.​

Answer 1

• 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
