TRY IT Solve a Problem Using Two trains leave a station on different tracks. The
tracks make an angle of 115° with the station as a
vertex. The first train travels 200 kilometers and
makes its first stop in Pocomoc, while the second
train travels 350 kilometers and makes it first stop
in Easton. How far apart are the trains when both
are at their first stop? Round the answer to the
nearest tenth.

109 is the nearest whole number/final answer! : )

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

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
