    As a starter, draw the problem. With the tower on one side (doesn't matter about the height) then draw an imaginary line to indicate the 70° angle to the top of the "tower". Then draw a further line at 35° to the top of the tower. Then fill in what you know. Start with that and see if you can figure it out

    Use the law of tangents according to the diagram. Solve for x and y.
    y being the height of the tower.
