Answer:
x ≈ 57.8°
Step-by-step explanation:
The relevant trig relation is the one that relates the side adjacent to the angle to the hypotenuse and the angle:
Cos = Adjacent/Hypotenuse
cos(x) = 8/15
The value of x is found using the inverse cosine function:
x = arccos(8/15)
x ≈ 57.8°

Hello from MrBillDoesMath!
Answer: The other side has a length of 8
Discussion:
Area of a rectangle = l * w ( length times width). In our case
Area = 144 = l * w = 18 * w =>
18 w = 144 =>
w = 144/18 = 8
Thank you,
