OpenStudy (anonymous):

Using HG as a side and FG as a side, you can see that HFG forms a right triangle, correct? Then we just need to use the Pythagorean Theorem to find the hypotenuse, which is the length FH. We get (HG)^2 + (FG)^2 = (FH)^2 7^2 + 4^2 = (FH)^2 49+16=(FH)^2 65=(FH)^2 sqrt(65) = FH or FH ~8.06 units
