The interior angles formed by the sides of a hexagon have measures that sum to 720°.
ira [324]

Answer:

F=140

Step-by-step explanation:

Remember that all angles will be able to add to 720 so you should get something like this:

130+120+110+x-20+x-60+x-40=720      

Then solve for x to do this:

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

360-120+3x=720

3x+240=720

3x=480

x=480/3

x=160

With x=160, you can plug in to solve and find that F=140
