Angle 1 is an angle of depression because you start off looking directly horizontal and you look down to aim at the ground
Angle 3 is an angle of elevation. You start looking horizontally and then you look up
Roughly, the perimeter of the room, including the sitting area, would be 65.909 ft squared. The perimeter of the semicircle would be approximately 13.909 ft. Then, add it to the 24 (12 x 2) and 28 (14 x 2), and you get 65.909 ft squared. As for the area, it would 168 (12 x 14) + pi (3.1415...) x 6 squared (radius squared - radius is half of the diameter) divided by two (since it's a semicircle). So then, your answer would be about <span>224.54 square feet.</span>
The answer is 9.5 ( rounded, answer is 9.486833)
(x + 9) (x - 2)
= x^2 + 7x - 18☺
