<h3>What are the building construction members?</h3>
The architectural construction method that consists of two uprights and a crossbeam is called post-and-lintel system. This is because in building construction, a system in which two upright members, the posts, hold up a third member, the lintel, laid horizontally across their top surfaces.
The post-and-lintel system is a simple method of construction involving the use of vertical and horizontal elements. The verticals support the horizontals, creating one Storey of a building. Additional verticals can be placed atop the horizontals to create structures with more than one level.

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
