Answer:

15 ft

Explanation:

Use Pythagorean Thm. If I have two sides:

Then I do this to find the third:

If looking for leg, do sqrt(big square - small square)

If looking for hyp, do sqrt(leg square+leg square)

So what this means since x is a leg, I'm going to do sqrt(17^2-8^2)

17 was bigger than 8 that's why it went first

Anyways now we can just whip out the calculator

sqrt(17^2-8^2)=15

Since this is a right triangle you may use Pythagorean theorem which is
a^(2) +b^(2) =c^(2)

a and b are the legs (two sides that FORM the right angle) of the right triangle while c is the hypotenuse (the side that is opposite the right angle)

In this case...

a = x

b = 8

c = 17

Plug these numbers into the formula and solve for x


x^(2) +8^(2) =17^(2)


x^(2) + 64 = 289


x^(2) + (64 - 64) = 289 - 64


x^(2) = 225

To remove the squared from the x take the square root of both sides

x = 15

Hope this helped!
