Challenge! Ready? 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? http://assets.openstudy.com/updates/attachments/55ae81c9e4b0d48ca8ed889a-lollygirl217-1437500103490-as.jpg

    one way would be to find the middle angles by applying the cosine rule to the left side triangle . Then apply it to the one on the right to find length of FG.

    Cos x = 82^2 + 92^2 - 47^2 / (2.82.92) x = 30.66 degrees then FG^2 = 82.8^2 + 73.8^2 - 2* 82.8*73.8 cos 30.66 = 42.30

    the other one is 2 similar pentagons so corresponding sides will be in the same ratio
