In triangle ABC shown below, point A is at (0,0) point B is at (x subscript2, 0)
point C is ([x sub1]/ 2, [y sub1]/2
point D is [x sub1 + xsub2]/2, ysub1/2)

Prove that segment DE is parallel to segment AB.

Proof below

Step-by-step explanation:

To prove DE and AB are parallel, we compare the slopes of both segments

Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

Segment AB goes through the points (0,0) and (x2,0), thus:

The slope is 0 because the line is horizontal.

Now for the segment DE, the endpoints are

The slope is:

Segment DE is also horizontal, thus is parallel to segment AB.

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51
