Start using assigning a variable, and literal translation.

Given x is the shorter leg. 
SEGMENT OR SIDE          NUMBER
short leg                  x
long leg                 -9+3x
hypotenuse                1+2x


If legs of a right triangle are a and b, and if hypotenuse is c, then we have a relationship among them, a%5E2%2Bb%5E2=c%5E2, Pythagorean Theorem Right Triangle Formula.
