Answer 7

Since you don't seem to be online, I'll give you the following hints:
From the right triangle with sides 8 and 17, you can find, using Pythagoras Theorem, the third side, which is perpendicular to the side which measures 8 units. Call it y.
For the smaller triangle, the side lengths are y and (8-3)=5.
From y and 5, you can again use Pythagoras Theorem to find the unknown side x.
(hint: x is not an integer).
