#19. A fortress has been built on top of a cliff. You measure the angle of elevation of the top of the cliff from a point 200 meters horizontally away from the base of the cliff to be 30° and the angle of elevation of the top of the fortress wall from the same point to be 45°. What is the height of the fortress wall?

Convert each Rectangular coordinate into two distinct Polar coordinates (r, 0) each. (Use degree) A. (-1,1) B. (0, -3) C. (-√3,-1) D. (2.5, 5) :: (0, 45") (1.41, 135) :: (5.59, 63°) :: (3, 90°) :: (2, 30°) = (0, 180°) :: (1.65, 30°) :: (2, 210") :: (3, 270°)

Calculate X

An aircraft (at Z) is spotted by two observers (at X and Y) who are L = 2000 feet apart. As the airplane passes over the line joining them, each observer takes a sighting of the angle of elevation to the plane, as indicated in the figure. If A = 40°, and B = 20°, how high is the airplane? %3D A Y B.
