Campsites F and G are on opposite sides of a lake. A survey crew made the measurements shown on the diagram. What is the distance between the two campsites?

Answer:
a. 42.3 m
Step-by-step explanation:
so this exact picture isn't the one on my test, but it would have to be greater than 38 because the line is longer. the question i got the measurement for the other side was 47. Hope this helps somebody :)
Using the theorem of similar triangles, the distance between the two campsites is: 41.8 m.
Recall:
Thus, the diagram that shows the measurements made by the survey crew tells us that two similar triangles are formed.
Thus:
40.7/37 = 1.1
42.9/39 = 1.1
This shows the two sides are proportional. Since both triangles share a common angle, then the third side in each triangle will also be proportional to each other.
Therefore, if x represents the distance between the two campsites, we will have the following proportion:
[tex]\frac{x}{38} = 1.1[/tex]
x = 41.8 m.
Therefore, using the theorem of similar triangles, the distance between the two campsites is: 41.8 m.
