It's a right triangle, so you can use the pythagorean theorem.

2. anonymous

ohh ok ....so...then what?

3. anonymous

The equation is$leg^2+leg^2=hypotenuse^2$

4. anonymous

or$14^2+x^2=20^2$

5. anonymous

6. anonymous

No...how do you figure that?

7. anonymous

8. anonymous

XD

9. anonymous

$x^2=20^2+14^2$ $x^2=400-196$ $x=\sqrt(204)$

10. anonymous

204?

11. anonymous

i thought we were supose to add it?

12. anonymous

not quite, you need to use algebra to solve this one, you subtract 14^2 from both sides to get the variable on its own, then take the square root of the whole equation to get the final answer which is x=14.3

OHH OK THANKS

14. anonymous

You're welcome!
