Question

Find the value of x.

Answer 1

Alright so first, what math level is this for?

Answer 2

This is geometry

Answer 3

Ahh okay, so the way we would go about this is to realize this is a special triangle

A right triangle...with one side as 60 degrees....makes this a 30-60-90 triangle



So this is your triangle

if we compare it to the triangle given to show that it is special...

Answer 4

if you see those annoying question mark symbols in the picture...refresh your page...hate that >.< lol

Answer 5

okay xD

Answer 6

theyre gone now lol

Answer 7

Lol alright, so looking at that second triangle...it says

If the bottom side is SOME number 'x'

Then the side that is the hypotenuse would be '2x' Or TWICE that number...

So comparing that to your triangle, if your 2x = 8....then what is the 'x' ?

Answer 8

umm idk /.\ sorry im a little confused

Answer 9

Okay...hmm lets see if I can make it any better...

Answer 10

So if you like...google something about special right triangles...you will get a couple results since there are a couple...but this specific one is a 30 60 90 triangle

So if you look that up, you will see a picture of

Answer 11

Again with the refresh :P

Answer 12

ok

Answer 13

wait would x be 4?

Answer 14

but okay, if we look at that...we have an 'x' on the bottom....we have a '2x' on the right side....and we have a 'x√3'on the left

This means...if we make 'x' be some number....we can see the other 2 sides...

Example...if I say x = 3

Answer 15

yes x would be 4 /.\ lol

but do you see why now? maybe? lol

Answer 16

ooooooh ok yes /-\ lol
