## anonymous one year ago which set of values can be the side length of a 30 60 90 triangle?

I'm not sure of your question: the values of the sides have to follow the formula of 30-60-90 triangles. I'm not sure if you want me to help you chose an answer if there are no options

2. anonymous

Short leg = (1/2)hypotenuse Long leg = (1/2)hypotenuse *sqrt(3)

A.{4,4r2,8} B.{4,4r3,8} C.{4,4r3,8r3} D.{4,4r2,8r2 sorry it took me so long this is my question here and i wasn't sure how to put radical in the equation so i just put r

4. anonymous

I'm guessing it goes in the order (short leg, long leg, hypotenuse) ?

5. anonymous

yeah its on a site called apex learning

6. anonymous

radical is what i meant

7. anonymous

so 4r2 = $4\sqrt{3}$

8. anonymous

*4r3

9. anonymous

how do u enter the radical symbol in the equation

10. anonymous

There's a blue button that says "equation" under the chat bar.

11. anonymous

Use the forumla I posted above

12. anonymous

Short leg = 0.5(hypotenuse) Long leg = 0.5(hypotenuse)*$\sqrt{3}$

13. anonymous

also, the hypotenuse is the longest side :P

14. anonymous

is there a way i could just send a picture of my screen... it would be a lot easier for you

15. anonymous

I know what you mean and the answer, don't worry about me.

16. anonymous

ok

17. anonymous

do you have your answer?

18. anonymous

no not yet

19. anonymous

Did you try to use what I posted above? Once you do it's very easy

20. anonymous

sorry but im not sure how to use it

21. anonymous

You know the short leg is 4, because that's the answer for all the options

22. anonymous

oh your right

23. anonymous

Find hypotenuse by multiplying by 2, and find the long leg by multiplying by sqrt(3)

24. anonymous

i dont know which number to multiply by 2 it doesn't show the hypotenuse

25. anonymous

The order goes like this: shortleg, shortleg*sqrt(3), shortleg*2

26. anonymous

ohh

27. anonymous

do you have the answer now :P

28. anonymous

workin on it...im just confused

29. anonymous

Here's a hint, because square root 2 isn't in the formula, you can eliminate all answers with square root 2

30. anonymous

soo that just leaves B and C right ?

31. anonymous

Yes, and short leg is 4, because 4 is the first number for all the options

32. anonymous

and hypotenuse = short leg*2, so the last number should not have a radical

33. anonymous

took a while, but I think you know the answer now :)

34. anonymous

oh please tell me B is the right answer

35. anonymous

Yes :)

36. anonymous

@\$#!@ yeahh!!! thnx for your help
