|  y=mX+b m= slope b= y-intercept. eali learn to use graphs. like now. also: A^2+B^2=C^2. oh and: (x`1-x`2) ----------- (y`1-y`2) | |

| Need to use Pythagorean theorem. Graph won't help much.

| Rika, y2 - y1 goes on top of x2 - x1. Trust me, y going on top cost me a test >.> | |

| ok so triangle APF is the only one you can work with. You can assume that since line AF, and line FE are equal, and CF insecates its perfectly, So it's a right triangle, so you can use the A^2 + B^2 = C^2 rule.
A^2 + 16 = 100
A^2 = 84
I don't have a technical calculator to finish that, but you can fill in a few numbers. | |

I don't have a technical calculator to finish that, but you can fill in a few numbers. some teachers will allow it so you can say "between 9 and 10" since the square root would be in btwn those 2 numbers...tho if you're allowed to use a calculator, use it | |
