How to Measure the Height of a Tall Object Using a Clinometer

This video tutorial explains how to measure the height of a tall object using a clinometer. It covers the steps to position oneself, use the clinometer to measure the angle of elevation, and apply trigonometric formulas to calculate the height above eye level and the total height of the object. The example used is measuring a flagpole, and the tutorial concludes with a summary and a reference to additional resources.

What is the first step in measuring the height of a tall object using a clinometer?

• Stand at the base of the object.

• Measure the height of the object directly.

• Position yourself at a distance from the object.

• Calculate the angle of elevation.

Which angle of elevation was recorded for the flagpole in the video?

• 90 degrees

• 60 degrees

• 45 degrees

• 30 degrees

What formula is used to calculate the height of the flagpole above eye level?

• cot x = l / x

• sin x = l / x

• cos x = l / x

• tan x = l / x

What is the value of tan 45 degrees used in the calculation?

• 0

• 0.5

• 2

• 1

What is the final calculated height of the flagpole?

• 5 meters

• 6.65 meters

• 7.5 meters

• 8 meters
