proportions. To measure the distance betweens points A and B, on two islands, a man takes the following measurements on one island: AC = 5 yds, DE = 6 yds, AE = 15 yds, how far apart are the islands?

    If anyone can please check this, I did it two ways with two answers: x/15 = 6/5 5x = 75 x = 15 yds (this was the first way) 5/6 = x/15 6x = 75 x = 12.5 yds ( second way) not sure if I'm lining up my ratios properly???)

    looks like it in the book... an island with water spaced to another island. its a right triangle from one island to the other... a line creates a right angle bisector at the end of the first island is the 5 yds

    tanB = tanB 6 5 ------ = ---- ; cross multiply now 15 +x x 6x = 75+5x x = 75
