How to find the distance a car travels with changing angle

The video tutorial explains how to solve a problem involving an observer on a 100-foot building watching a car approach. It covers the concept of angles of depression, the creation of right triangles, and the use of trigonometric ratios to calculate the distance the car travels. The tutorial demonstrates how to calculate and store values using a calculator, and concludes with the final distance calculation.

What is the height of the building from which the observer is watching the car?

• 150 feet

• 100 feet

• 75 feet

• 50 feet

Why is it important to use the top of the building as the horizontal reference line?

• Because it is a standard practice

• Because it is closer to the car

• Because the observer's height is unknown

• Because it is easier to measure

What is the purpose of creating right triangles in this scenario?

• To simplify the calculation of angles

• To measure the speed of the car

• To find the height of the building

• To calculate the distance the car traveled

Which trigonometric function is used to calculate the distances in this problem?

• Sine

• Secant

• Cosine

• Tangent

How is the distance the car traveled determined?

• By subtracting the two calculated distances

• By adding the two calculated distances

• By dividing the two calculated distances

• By multiplying the two calculated distances

What is the final calculated distance the car traveled, rounded to the nearest thousandth?

• 219.219 feet

• 300.300 feet

• 200.200 feet

• 250.250 feet

Why is it important to store values in a calculator during calculations?

• To avoid using paper

• To save time

• To ensure accuracy

• To make calculations faster
