Math 9 - Angle of Elevation

Front

What is the angle of elevation?

Back

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

Front

What is the tangent function in relation to right triangles?

Back

Front

How do you find the height of an object using the angle of elevation?

Back

To find the height, use the formula: height = distance * tan(angle of elevation).

Front

What is the sine function in relation to right triangles?

Back

Front

What is the cosine function in relation to right triangles?

Back

Front

What is the relationship between the angle of elevation and the height of an object?

Back

The height of an object can be calculated using the angle of elevation and the distance from the object using trigonometric ratios.

Front

If the angle of elevation is 48 degrees and the distance from the object is 50 feet, how do you calculate the height?

Back

Use the formula: height = 50 * tan(48°).

Front

What is the horizontal line in a right triangle?

Back

The horizontal line is the base of the triangle, which is adjacent to the angle of elevation.

Front

What does the line of sight refer to in the context of angles of elevation?

Back

The line of sight is the straight line from the observer's eye to the object being observed.

Front

How do you determine the height reached by a ladder leaning against a wall?

Back

Use the formula: height = distance from wall * sin(angle of ladder with ground).
