The answer is A) x = 9
We know this because every four sided figure has angles that measure up to 360. So we can subtract all of the angles and then use the remaining angle to solve the problem.
360 - 90 - 90 - 99 = 81.
So with the remaining angle being 81, we can solve for x.
x^2 = 81
x = +/-9
Since +9 is the only answer that makes sense in this case, x = 9.
18 + 45m

To do this you have to fill in the equation

, but you don't know the height, so we'll use

for height. Plugging in the numbers you gave me, the equation is:

. To solve this, we need to find

. To find height you do

. Doing this, we get

=
3.75 ft.Hope this helped!
