False!

In a 30-60-90 triangle, the hypotenuse (c) is twice the length of the shorter leg (a): c = 2a
In a 30-60-90 triangle, the longer leg (b) is equal to the shorter leg (a) multiplied by √3: b = a√3

What number do you divide by 12 to get 9

finlep [7]

Well I don't know. Let's figure it out together.

You said (a number) divided by 12 gives you 9 .

A fraction is the easiest way to show division, so
you can write this equation:

 (number) / 12 = 9

Now you can multiply each side of the equation by 12 .
When you do that, you have ...

 number = 9 x 12

 number = 108 .

Now you know how to find it. That's even better than just
having the answer.
