A 20-foot ladder is leaning against a building. The ladder forms an angle of 55" with the ground.
Part A: How far away from the building is the bottom of the ladder? Round the answer to the nearest tenth.
Part B: How far up the building does the ladder go? Round the answer to the nearest tenth.
Part C: If the ladder is repositioned, and the base is now 9 feet from the building, what is the new angle that the ladder makes with the ground? Round the answer to the nearest tenths place.
