Answer 2

use Pythagorean theorem, you have right triangle, find hyp which is segment PQ

Answer 3

I used the Pythagorean theorem and i still didn't seem to the right answer @ivettef365

Answer 4

ok you have one side = (from 6 to 10) = 4
the other side = 12
so you have

4^2 + 12^2 = c^2 solve for c

Answer 5

what do you get ??
