You have to do Pythagorean theorem:

"a" and "b" are the legs. In this case 7 is a leg and x is a leg
"c" is the hypotenuses, which is 19 here
so...
a = 7
b = x
c = 19
Plug the numbers above into the equation:


Isolate x by subtracting 49 to both sides:


To solve for x you have to take the square root to both sides of the equation:

x = 17.6635
x = 17.7
Hope this helped!

You would want to make it so it has 12 on the bottom. So you would multiply by 12. Which is 84. The you put it over 12. So it would be 84/12.

9 puppy bots + 6 kitty bots = 15 total bots
15 total bots x 4 wheels = 33 total wheels
