The point A is directly below a window. Another point B is 15 m from A and at the same horizontal level. From B angle of elevation of the top of the bottom of the window is 300 and the angle of elevation of the top of the window is 350. Calculate the vertical distance.
(a) From A to the bottom of the window (b) From the bottom to top of the window
I guess 360 is straight up ?
tan 30 = h bottom/ 15
tan 80 = h top / 15
