The interior angles formed by the sides of a hexagon have measures that sum to 720°.
1 answer:
Answer:
Angle F = 140°
Step-by-step 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°
