Question

The interior angles formed by the sides of a hexagon have measures that sum to 720°.

What is the measure of angle F?

Enter your answer in the box.

​m∠F=​

Answer 1

Explanation:

(x-60)+(x-20)+(x-40)+130+120+110=720

3X -120 + 360=720

3x +240= 720

3x= 720-240

3x=480

x= 480/3 = 160

x=160

angle F = (x-20)

angle F = 160-20=140

angle F = 140
