You have to do Pythagorean theorem:

a^{2} +b^{2}  = c^{2}

"a" and "b" are the legs. In this case 7 is a leg and x is a leg

"c" is the hypotenuses, which is 19 here

so...

a = 7

b = x

c = 19

Plug the numbers above into the equation:

7^{2} + x^{2} = 19^{2}

49 +x^{2} = 361

Isolate x by subtracting 49 to both sides:

(49-49) + x^{2} = 361 - 49

x^{2} = 312

To solve for x you have to take the square root to both sides of the equation:

\sqrt{x^{2} } = \sqrt{312}

x = 17.6635

x = 17.7

Hope this helped!
