  1. Sketch the 2 buildings, mark the window on one of them.
    Draw a horizontal from the window to the other building, mark it as 15m
    (any horizontal line between the two buildings will be 15m )
    From the window draw in lines to the top and bottom of the opposite building.
    Mark your given angles. You have right-angled triangles.

    Btw, I see no question asked in your problem.
