An engineer creates a solid steel for an engine. The part has a volume of 1450 cm ^ 3 . Steel can be purchased for $0.35 per kg, and has a density of 95g/cm^ 3 If the engineer makes 350 of these parts, what is the cost of the steel to the nearest dollar

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

i dont know what you want me to answer for this but im guessing 2: 11?
