???

2. binarymimic

can you determine the lengths of the sides?

3. Jovanmommy_13

huh

4. binarymimic

the lengths of the sides means how long each side is

5. Jovanmommy_13

i'm confused on how to get the answer

6. binarymimic

do you know how to determine a length when you have two points ?

7. Jovanmommy_13

not one bit,

8. binarymimic

there are a few ways to do this. but the easiest is just use the distance equation $distance = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}$ the points on the hypotenuse of that triangle are (4, 2) and (-5, -3) it looks like so just calculate the distance between those two points

are you in conexus

10. binarymimic

that's the easy way. the other way is to calculate the lengths of the sides separately just by looking at the picture, the length of the top side is 9 and the length of the left side is 5 9^2 + 5^2 = c^2

11. Jovanmommy_13

i don't know what conexus is but it called graphing data for my work?

12. binarymimic

|dw:1359037431903:dw| maybe that will help ?

13. Jovanmommy_13

25+81? = the answer? or is there more?

14. binarymimic

no you have to solve for 'c'

15. binarymimic

25 + 81 = c^2

16. Jovanmommy_13

106^2 =11236 ?

17. binarymimic

|dw:1359037636202:dw|

18. Jovanmommy_13

Ha yeah i don't get this

19. binarymimic

this is how you solve for c

20. binarymimic

hm. you should review Pythagorean theorem

21. Jovanmommy_13

10.295630141?

22. binarymimic

yes thats right

23. Jovanmommy_13

do i just put 10.29 though?

24. binarymimic

no you'd have to round to the nearest hundredth. it would be 10.30

25. binarymimic

because 10.295... rounds up to 10.30, that's why

26. Jovanmommy_13

Oh, thanks,
