04.01 Using the Coordinates

Which statement explains how you could use coordinate geometry to prove the opposite sides of a quadrilateral are congruent?

A. Use the slope formula to prove the slopes of the opposite sides are the same.
B. Use the slope formula to prove the slopes of the opposite sides are opposite reciprocals.
C. Use the distance formula to prove the lengths of the opposite sides are the same.
D. Use the distance formula to prove the midpoints of the opposite sides are the same.

answer: add the !

step-by-step explanation: then we will answer

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
