It says to find the height of a trapozoid with bases equal to 10ft and 18ft, I don't know to find the height though!
Can anyone give me a formula?

You don't have enough information to find the height. You would also need to know the area, or the angle that the other two sides make with one of the bases.

The use of trig applies here!
If you have the degrees of one side of the trap and half the base you can use the degrees converted into a linear measurement usually comes out with a decimal point. The one side of an angle such as this from top to bottom is your co-sine and the base is your sine. So TANGENT= SINE X COSINE to find the height. Whereas to find sine or co-sine SINE= TANGENT divided by CO-SINE or CO-SINE = TANGENT divided by SINE

Does it give you the area? If so you can use this:
A = [h(a+b)] / 2 with a and b the sides and A as the area
change to:
h = 2A / (a+b)
The only other formula is if you know the lengths of the diagonal sides too.

I'd measure it...
