Ed is on a road trip he has already traveled 211 miles driving at a rate of 63 miles per hour which equation could be used to find how many hours x ed has left in his road trip if he is traveling 638 total times A. 63x + 638 = 211
B. 63x + 211 = 638
C. 211x + 638 = 63
D. 211x + 63 =638

can you add an image ?

step-by-step explanation:

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

the answer i believe is 27 units.
