The angle of elevation of the ground is the angle between the ground and the line of sight
The angle of elevation of the ground is 30.46 degrees
<h3>How to calculate the angle of elevation</h3>
The angle of elevation is calculated using the following tangent ratio

Evaluate the quotient

Take the arc tan of both sides

Using a calculator, we have:
= 30.46
Hence, the angle of elevation of the ground to the nearest tenth of a degree is 30.46 degrees

Based on the calculations, the pressure of this gas sample at 27°C is equal to 0.17 atm.
<h3>How to determine the final pressure.</h3>
In order to calculate the final pressure of an ideal gas at constant volume, we would apply Gay Lussac's law.
Mathematically, Gay Lussac's law is given by this formula;

<u>Where:</u>
- k is the constant of proportionality.
Substituting the given parameters into the formula, we have;

Final pressure = 0.17 atm.
