The tallest freestanding structure is the CN tower in Toronto Canada. From ground level the angle of elevation from point A to an object on the observation deck of the CN tower is 75 degrees. 111 feet away from point A, the angle of elevation is 70 degrees. Find to the nearest foot, the height of the observation deck of the CN Tower.

From a 111 feet away from point A, the angle of elevation is 70 degrees. I did not write that in because it was worded weird to me...now I think it's a distance reference of a side..sorry if that added confusion.

Perfect, I can get 1,309.14' now. And I think I understand why you did 180-75. = corner angle with a right triangle must =180. You took that difference and basically did the same thing to the other angle corner getting a degree of 5.
