Identify a pair of skew segments in the diagram. The figure shows two equal rectangles A E H D and B F G C in a space. The rectangles are located on parallel planes. Vertex A corresponds to vertex B. Vertex E corresponds to vertex F. Vertex H corresponds to vertex G. Vertex D corresponds to vertex C. The corresponding vertices are connected with segments. An angle between segment A B and segment A C measures 90 degrees. Segment C D is parallel to segment G H.

answer: 230 miles ( vote ! )

step-by-step explanation:

180.39 minus 17.99 equals 162.4

then divide 162.4 by .80 to get 230

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

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
