Step-by-step explanation:
I hope this helps...
A = 192 in²
The area (A) of a trapezoid is calculated as
A = h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 12, b₁ = AB = 14 and b₂ = DC = 2 + 14 + 2 = 18, then
A = × 12 × (14 + 18) = 6 × 32 = 192 in²

0.791 < 0.971
There you go. I just drew it to make it easier than giving coordinates
x=10
43 and (4x+3) are vertical angles, which mean they are equal
so, 43=(4x+3)
43-3=(4x+3-3)
40=(4x)
40/4=4x/4
10=x
