FROM A DISTANCE OF 80 M. THE ANGLE OF ELEVATION OF THE TOP OF A FLAGPOLE IS 18 DEGREES. dETERMINE THE HEIGHT OF THE FLAGPOLE.(NEAREST TETH OF A M.
mY CONFUSION IS ANGLE OF DEPRESSION AND ANGLE OF ELEVATION. mY TECHER CALLS FROM TOP ELEVATION WHILE i INSIST ELEVATION IS FROM THE BOTTOM.
The height is 80 tan 18.
The angle of depression of the observer as seen from the top is the same as the elevation angle of the top as seen by the observer. (Assume the observer's height is zero, or add it to 80 tan 18)posted by drwls
