Answer:
x = 67.1°

Step-by-step explanation:
The triangle modeling the given scenario is shown in the attached picture.

Now, the given triangle is a right-angled triangle. This means that special trig functions can be applied.
These functions are as follows:
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent

Now, in the given triangle we have:
θ = x
hypotenuse = 72 feet
adjacent = 28 feet

Therefore, we can apply the cos function to get the angle as follows:
cos x = 28/72
cos x = 7/18
x = cos⁻¹(7/18)
x = 67.11 which is 67.1° to the nearest tenth.

Hope this helps :)
