    It's a right triangle, so you can use the pythagorean theorem.

    \[x^2=20^2+14^2\] \[x^2=400-196\] \[x=\sqrt(204)\]

    not quite, you need to use algebra to solve this one, you subtract 14^2 from both sides to get the variable on its own, then take the square root of the whole equation to get the final answer which is x=14.3
