You know the missing side of the bottom base is 6 because of the 30 60 90 special right triangle. The height is 6sqrt3 because of what i said above too, The area of a trapezoid is 1/2 b1+b2*h so 30+36*6sqrt3 is 396sqrt3 divided by 2 is 298sqrt3
You mean, what is this number?
we can rephrase it like this: the sum of a number x and 8 is 15
which is:
x+8=15
we subtract 8 from both sides and we get
x=7
so the answer is 7.

Step-by-step explanation:
<u>Step 1: Define</u>
Ax + bx = c
<u>Step 1: Solve for </u><em><u>x</u></em>
- Factor: x(A + b) = c
- Isolate <em>x</em>: x = c/(A + b)
We know that we cannot divide by 0, so A + b cannot equal 0.
16 and 72 would be the answer
the relationship between the two columns would be +2
hope this helps :)
