I’m attaching a photo. For each of these, start by multiplying both sides of the inequality by what’s in the denominator.
When drawing of the number lines, the circle is filled in if the any quality has an “equal than.” Otherwise, the circle is left open.
When dividing by a negative number, the direction of the inequality flips. Greater than becomes less than, and vice-versa.

Answer:
53.52°
Step-by-step explanation:
The cosine function relates the angle to the sides shown:
Cos = Adjacent/Hypotenuse
cos(x°) = (22 ft)/(37 ft) = 22/37
The inverse cosine function is used to find the corresponding angle.
x° = arccos(22/37) ≈ 53.52°
