Answer:
The length of 2 wires are 13 feet and 12 feet [i don't know if the 3rd side is a wire, if so, the length is 5 feet]
Step-by-step explanation:
<em>The image of the tent is attached.</em>

As we can see, it creates a right triangle with "x+8" side being the hypotenuse of the triangle.
The pythagorean theorem tells us:
Hypotenuse^2 = Leg^2 + Leg^2
THe hypotenuse is "x+8", the two legs are "x" and "x+7" respectively. Let's solve for x:
We expand and solve for x:
Length can't be negative, so x = 5.
Hence, the 3 sides of the triangle are:
x = 5
x + 8 = 13
x + 7 = 12
The length of 2 wires are 13 feet and 12 feet
