III. 7, 13, 229
A I, II and III
B. II only
C. I and II only
D. None of the above
6. Three students draw triangle with the side lengths shown. All three s
triangle. Which of the students are incorrect? What mistake might they
PLS HELP

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

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

idk what the heck he answer is, i’m just putting this here so i finish my account
