anonymous · Answer

I put "x" for base one and just worked it out

anonymous · Answer

Here: 
A=1/2×h (base one + base two)
A= 1/2×6 (x+8)
A=3(x+8)
A= 3×8 + 3× x
A= 3x + 24 = 36 
            - 24.  - 24
A= 3x = 12
Divide 3 on both sides and it ends up leaving you with
X= 4
after that I just checked my work by plugging it into the formula.
