Question

A point is directly below a window. Another point B is 15 m from A and at the same horizontal level. From B angle elevation of the top of the bottom of the window is 300 and the angle elevation of the top of the widow is 350. Calculate the vertical distance.
(a) From A to the bottom of the window
(b) From the bottom to top of the window.

Answer 1

The exposition is rather garbled, but I take it that

A is x below the window
The window has height h

x/15 = tan 5°
(x+h)/15 = tan 35°

Now you can answer the questions. (I think)
