first, find the intersections of the parabolas using any method. i choose to use the elimination method
next, find the distance between the intersected points (3, -1) & (-1, 2):
b is the correct answer becuase the definition of an adjacent angle is two angles that have a common side. hvi and ivj are the only two options that are adjacent angles. hope this !
answer: it would be 20
area = 1/2 * sum of the parallel lines * height
= 1/2 * (3+8+3+8) * 12
= 1/2 * 22 * 12
= 132 in^2.
