Triangle ABC is congruent to triangle CDE using the side - angle - side congruence theorem. The sink hole is 52.2 ft and the Perimeter of ABC is 172.2 ft

<h3>What are congruent triangles?</h3>

Two triangles are said to be congruent if they have the same shape and their corresponding sides are congruent.

In the image shown:

AC = CE, BC = ED and they have the same angle (opposite angles are congruent).

Hence:

Triangle ABC is congruent to triangle CDE using the side - angle - side congruence theorem.

AB = DE = 52.2 ft

Perimeter of ABC = AB + BC + AC = 50 + 70 + 52.2 = 172.2 ft

What is the description of angle 4 as it relates to the situation below?

Murljashka [212]

Answer:

The correct option is 1.

Step-by-step explanation:

The angle of elevation is the angle formed by the line of sight and the horizontal plane for an object above the horizontal.

The angle of depression is the angle formed by the line of sight and the horizontal plane for an object below the horizontal.

Since the angle 4 is the angle between the line of sight and the ground for an object above the horizontal, therefore angle 4 is the angle of elevation from the person to the radar tower.

1. "Angle 4 is the angle of elevation from the person to the radar tower."

This statement is true.

2. "Angle 4 is the angle of depression from the radar tower to the person".

This statement is is false.

3. "Angle 4 is the angle of depression from the person to the radar tower".

This statement is false.

4. "Angle 4 is the angle of elevation from the radar tower to the person".

This statement is false.
