Question

when sitting atop a tree and looking down at his pal Joey, the angle of depression of Mack's line of sight is 53degrees 51inch. If joey is known to be standing 25 feet away from the base of the tree, how tall is the tree (to the nearest foot.) Who ever answer this plz do it thoroughly because i would like to undertand these type of questions easier

Answer 1

Assuming that Mack is looking at Joey's feet, draw a diagram. It should be clear that if the tree's height is h, then

h/25 = tan 53°51"

Now just get out your calculator...
