A ladder is leaning against the outside wall of a building. The figure below shows the view from the end of the building, looking directly at the side of the ladder. The ladder is exactly 12 feet long and makes an angle of 60° with the ground. If the ground is level, what angle does the ladder make with the side of the building? _____________


How far up the building does the ladder reach (give an exact value and then approximate to the nearest inch)? Hint: Use a known trigonometric ratio to solve this problem. __________________
