What is the question

anonymous · Answer

sure

anonymous · Answer

What is the length of the bar AC?

6 sin 60°

6 cos 60°

6 by cos 60 degrees

6 by tan 60 degrees

anonymous · Answer

easy 
 nd btw im a 6th grader lol

anonymous · Answer

noot sure i dont want to be wrong

anonymous · Answer

Do you know soh cah toa

anonymous · Answer

I think it is 6 by tan 60 degrees

anonymous · Answer

But how would you work it out?

anonymous · Answer

this should help 
because it is a 30 60 90 triangle just plug in your terms

anonymous · Answer

if the hypotenuse is 2x and we are given the measurement it means that:
2x=6 then solve for x and you have the length of AC

anonymous · Answer

So would the length of AC be 3?

anonymous · Answer

Im not sure lol im only a 6th grader thats good at math sometimes
if they need an aswer 
 respond with something that has to do with degreees

anonymous · Answer

Yes

anonymous · Answer

Which would be equal to 6 by cos 60 degrees?

mrnood · Answer

Just start with the triangle.

I assume you are working on sin cos and tan

Here is the drawing 'simplified':
|dw:1396636720652:dw|

The adjacent is AC

One of those formulae will give you the equation to find Adjacent  you know theta(60) and H (6ft)

anonymous · Answer

So the answer should be 6 by cos 60 degrees?

anonymous · Answer

@MrNood

anonymous · Answer

yes 
 lol
 it should 
 my teacher said yes

mrnood · Answer

Yes.

And cos 60 = ?

anonymous · Answer

3?

anonymous · Answer

Yup

anonymous · Answer

Great job.
