The first thing you can do is divided 6 by 2 and get 3. Since you drew a line in the middle to create 2 right triangles. |dw:1343416795252:dw|

Can you figure out the rest from here using the formula a^2+b^2=c^2??

4. anonymous

pythagorean theorem

5. anonymous

so what is 3^2+4^2?

6. anonymous

144

7. anonymous

How did you get that? I got a different answer.. 3x3+4x4=

8. anonymous

nvm you're right.

9. anonymous

wait..

10. anonymous

3x3+4x4=25, but you did 3x3x4x4=144.. See the difference?

11. anonymous

ok

12. anonymous

so anyways, it's 25. $\sqrt{25}=5$

13. anonymous

so now you know one side, so you should know the other side
