For trapezoid, the area = (upper base + lower base) * height / 2
So area = (12 + (2*2 + 12) ) *13 / 2 = 182
The correct answer is
D) 1/2
because
5/10 = 1/2
The inside angles of the triangle add to equal 180 and so does m/FEG with unknown triangle angle.
x+2x = x+40
2x = 40
x = 20
mFEG
= 20 + 40
= 60
