We can use the Pythagorean theorem to help us solve this problem: where c is the longest side of a right triangle (the hypotenuse) and a and b are the other two sides
It's safe to assume that x is the longest side in this triangle, making it the c value. Plug 14 and 9 into the equation as a and b and solve for x:
Therefore, the value of x is 16.6 units when rounded to the nearest tenth.
