Step-by-step explanation:

You need to draw a right triangle as the one attached, where is the angle of elevation from the fire to the top of the fire tower.

You need to use the Inverse trigonometric function Arctangent:

Observe the triangle. You can identify that:

Then, you can substitute values:

Finally, evaluating, you get that the angle of elevation  from the fire to the top of the fire tower is the following:

Rounded to the  the nearest tenth of a degree:
