...Well basically the questions are
A hawk is on top of a tree looking down at a mouse with the angle of depression at 63 degrees. 20 feet below the hawk, an owl is looking at a mouse with an angle of depression at 48 degrees. What is the height of the tree?
let x = horizontal distance from the tree to the mouse
solve the system for h
y=xsquared tan x is the function positive, negative, or neither?
you sure you don't mean odd, even, or neither?
