An engineer wanted to approximate the width, in feet of a river. she placed markers at point A and point B to represent the average width of the river. She also placed 3 other markers along the riverbank and measured the distances shown in the diagram below.
Based on this diagram, what was the width of the river, in feet, from point A to point B?

Label the two triangles and see which angles are equal................The sides corresponding to equal angles are proportionaldw:1337277341870:dw here AB:AC = BE:CD

U do not need AD................The equation AB:AC = BE:CD can be written as x/(x+49)= 62/93 Solve for x (Remember x = AB)

\[\left[\begin{matrix}x & 62\\ x+49 & 93\end{matrix}\right]\]

like okay.. x + 49 = AC,, so... ugh sorry i dont get math easily
