​m∠F=​
°

Answer 1

Angle F = 140°

Explanation:

Add up all the angles and set it equal to 720°

x-20+x-40+x-60+130+120+110=

720

Add the x's together. And the numbers together.

3x - 120 + 360 =720

3x + 240 = 720

Subtract 240.

3x = 480

Divide by 3.

x = 160

Now find Angle F.

F = 160 - 20

F = 140°
