What is the x-coordinate of the midpoint of the segment whose endpoints are
(2, 3) and (-5, 5)?

(-3/4, 4)

Step-by-step explaination:

add 2 and -5 then divide them by two and get

-1/2

then add 3 and 5 divide them by two and get

11/2

But as long as you remember that you're averaging the two points' x- and y-values, you'll do fine. It won't matter which point you pick to be the "first" point you plug in. Just make sure that you're adding an x to an x, and a y to a y.

so therefore the answer is (-3/4, 4)

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
