If we cut the triangle in half vertically down the middle, we get this triangle:

Since we can see that the triangle has legs of 8 and 6 with a hypotenuse of x, we can use Pythagoreans theorem to find the unknown side.

Pythagoreans theorem:

where a and b are the legs of the triangle and c is the hypotenuse

Plug in a=8, b=6, and c=x. Now lets solve for x

Square each individual term

Combine like terms

Take the square root of both sides

Simplify the square root

So the hypotenuse of this triangle is 10

Since we cut the triangle in half, this means the other triangle's hypotenuse also has a length of 10

After putting the two triangles back together, we have this triangle:

Since the figure was pointing to one side, I'm assuming that the problem is asking about one side. So the length of one pipe is 10 ft.
