h / Da = tan(25º)
Da / 42 m = tan(30º)
h = 42 m * tan(25º) * tan(30º)
I have been stuck on this for hours. Please help!!
During a nature trip, Joni, Billy, and Larry documented the location of an eagles nest. From point A, the campers observed the eagles nest on top of a tree, directly across a deep stream. The angle of elevation of the nest from point A is 30°. The campers walked 42m downstream to point B, and observed that the straight line to the base of the tree makes an angle of 25° with the path on the bank of the river. How high is the eagles nest above the ground?
