It would help if you had a four quadrant graph, but the distance would be (8,11).
Answer:

Step-by-step explanation:
x and 52 are supplementary, so they add up to 180°

Answer:
d. -7/25
Step-by-step explanation:
π<θ<3π/2 in third quadrant
tanθ = 4/3
sinθ = - 4/5
cosθ = - 3/5
cos 2θ = cos²θ - sin²θ = (- 3/5)² - (- 4/5)² = 9/25 - 16/25 = - 7/25
4.2 ft = 525 meters.... So 1 ft = 525÷42=125 meters
