Question

determine which two angles in the diagram below are angles of elevation.

2 and 4
1 and 3
1 and 4
2 and 3

Explanation:

Define angle of elevation

An angle of elevation is the angle formed by a horizontal line of sight and an observer's line of sight to an object that is above the horizontal line.

Analyze each angle in the diagram

• Angle 1: Formed between the bottom horizontal line and the line of sight looking upwards. This is an angle of elevation.
• Angle 2: Formed between the middle horizontal line and the line of sight looking downwards. This is an angle of depression.
• Angle 3: Formed between the middle horizontal line and the line of sight looking upwards. This is an angle of elevation.
• Angle 4: Formed between the top horizontal line and the line of sight looking downwards. This is an angle of depression.

Identify the correct option

The two angles of elevation are Angle 1 and Angle 3.

Answer:

• 2 and 4
• 1 and 3 (Correct answer)
• 1 and 4
• 2 and 3
