1. the westland lysander was an aircraft used by the royal air force in the 1930s. here
are some scale drawings that show the top, side, and front views of the lysander.

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

what is the information provided?

step-by-step explanation:

the answer to 1/4x+5/3x-4=2-1/12x is x=3
