Answer:
12
Step-by-step explanation:
Use pythag to solve.
x^2+5^2=13^2
x=12
Divide 224 by 8 and you will get 28.
Since all the sides add up to 10x+2, that means that 10x-2-<side1>-<side2>=<side3>. Plugging it in, we have 10x-2-5x-(2x+9)=side3, and 5x-2-(2x+9)=side3, then expanding it to 5x-2-2x-9=3x-11=side3
