AC= 6
This is a special right triangle with angles 30 60 and 90 degrees. There are special rules that allow you to figure out the side measurements when you only know one side!
Here, we know the measurement of the hypotenuse. Therefore, if we divide the hypotenuse by 2, we can get the measurement of the shorter leg.
4sqrt3 / 2 = 2sqrt 3
And now since we now the length of the shorter leg, we can take that measurement and multiply it by sqrt3 to get the measurement of the longer leg!
2sqrt3 x sqrt3 = 2sqrt9
The sqrt of 9 is 3 so we now have 2(3), which equals 6
X= 6
