The drawing seems to suggest that angles BFA, AFE and EFD span a straight angle, just like angles BFC and CFD
This means that you have

But we know that both BFA and EFD measure 70 degrees, so the equation becomes
![[tex]70+AFE+70=180 \iff AFE + 140 = 180](https://tex.z-dn.net/?f=%20%5Btex%5D70%2BAFE%2B70%3D180%20%5Ciff%20AFE%20%2B%20140%20%3D%20180)
So, if you subtract 140 from both sides, you have

Answer:
2,1,0
Step-by-step explanation:
9.647 x 10^7 should be the unrounded answer
Answer:
6
Step-by-step explanation:
#1: 4x - 8 = 16 (You want to remove -8)
#2: 4x = 24 (In order to remove -8 you need to cancel it out, add 8 to -8, also add 8 to 16)
#3: 4x = 24 (Now you need to get the x by itself, divide 4x by 4 to only get x and also divide 24 by 4)
#4: x = 6
Rule of Thumb: If you do something to one side, to it to the other :)
