Questions & Answers

Q: How can you calculate the height of a building using trigonometry?

To calculate the height of a building, you need the angle of elevation and the distance from the base of the building. You can use the tangent of the angle multiplied by the distance to find the height.

Q: What is the formula to calculate the height of a building with two different angles of elevation and the distance between them?

The formula is H = (D * tan(α) * tan(β)) / (tan(β) - tan(α)), where H is the height, D is the distance between the angles, α is the smaller angle, and β is the larger angle.

Q: Can you provide an example using the formula to calculate the height of a building?

Sure, if you have angles of 30° and 40°, and a distance of 150 feet between them, you can plug these values into the formula to find the height of the building.
