Help please !:)

OpenStudy (anonymous):

You got it. :)

OpenStudy (anonymous):

Could you post your profile picture as a comment so I can see it better?

OpenStudy (anonymous):

I can't doesn't work, sorry:/

OpenStudy (skullpatrol):

It depends on what the third side is.

OpenStudy (anonymous):

Okay. I'll use what I can see. I'll try to solve, but like skullpatrol said, we'lll need a SAS measurement.

OpenStudy (anonymous):

Thank You both!:)

OpenStudy (skullpatrol):

Is the diagram drawn to scale?

OpenStudy (anonymous):

Yes

OpenStudy (anonymous):

Actually, we could use cos sin and tan to answer. I'll get the answer right away! :D

OpenStudy (skullpatrol):

Just use a ruler and measure it. If you know how long 4 units is then you can solve for x.

OpenStudy (anonymous):

Yeah... That might be a little easier to do.

OpenStudy (anonymous):

Yeah, I'm not sure it's drawn to scale://

OpenStudy (anonymous):

Oh. Scratch that then xD

OpenStudy (skullpatrol):

Assume that it is.

OpenStudy (anonymous):

Ok, what will be the next step

OpenStudy (skullpatrol):

Measure how long the length of the 4 side is.

OpenStudy (anonymous):

I don't have a ruler at the moment :///

OpenStudy (skullpatrol):

Find one.

OpenStudy (anonymous):

Ok give me a minute

OpenStudy (anonymous):

4 cm

OpenStudy (anonymous):

Anyone there?

OpenStudy (skullpatrol):

Good. Now measure the side labeled x

OpenStudy (anonymous):

3

OpenStudy (skullpatrol):

cm?

OpenStudy (anonymous):

Yes

OpenStudy (skullpatrol):

So, 3 is your answer. Because of the proportion 4cm/4 = 3cm/x x = 3

OpenStudy (anonymous):

These are the answer choices: 2, 4sqrt2, 2sqrt 2, and cannot be determined

OpenStudy (skullpatrol):

Definitely "cannot be determined."

OpenStudy (anonymous):

Oh even though if my measurements weren't accurately correct right ?

OpenStudy (skullpatrol):

Yes, they depend on "scale."

OpenStudy (anonymous):

Oh ok so it's definitely cannot be determined, thank you so much! I appreciate it!

OpenStudy (skullpatrol):

Thanks for trying to learn :-)
