Equations:
y = 20x
y = 20x + 10
y = 20x - 15
The second and third graphs are related to the first graph by having parallel slope, due to the increase in cost total is $20/month.

Answer:
72.5° ≈ 73°
Step-by-step explanation:
The ladder length is the hypotenuse of the right triangle that has the distance from the building as its base and the height up the building as the height of the triangle. The given dimensions are those of the side adjacent to the angle and the hypotenuse.
The appropriate trig relation is ...
Cos = Adjacent/Hypotenuse
cos(angle) = 6/20
The inverse cosine function (arccos) is used to find the angle from its cosine.
angle = arccos(6/20) ≈ 72.54°
The angle is 72.5° rounded to tenths, or 73° rounded to degrees.
