Through pythagoras:

Because the square of the two sides add up to the square of the hypotenuse in a right triangle.
This means that



So the missing side is 16 inches
Hope this helped
To solve for x just isolate x by moving the other variables so....:
First add c to both sides
g+c= y+x
Subtract y from both sides
g+c-y= x
That should be your final answer (we cannot come up with an actual digit for x because there are no numbers in this equation we simply can make an equation for x)
