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
Hey! So I’m pretty sure you multiply 56 and 2, then you swap the sides of the equation. Answer: X=112
You will need to crest a graph first then place then variables
