Exam Review Solve word problem with changing angle

The video tutorial explains how to determine the speed of a plane using trigonometry. It starts by describing the plane's movement and the change in angle of elevation over time. The tutorial then guides through calculating the distance traveled using trigonometric functions and finally computes the speed by dividing the distance by time.

What is the initial angle of elevation observed by the student?

• 56.1 degrees

• 63.6 degrees

• 33 seconds

• 30,500 meters

What happens to the angle of elevation as the plane moves?

• It remains constant

• It increases

• It decreases

• It fluctuates

What is the altitude of the plane?

• 20,495.1 meters

• 15,140.3 meters

• 30,500 meters

• 33 meters

How is the distance D1 calculated?

• Using the cosine function

• Using the tangent function

• Using the secant function

• Using the sine function

What is the value of D2?

• 5,354.8 meters

• 30,500 meters

• 20,495.1 meters

• 15,140.3 meters

How is the speed of the plane calculated?

• By multiplying the distance by time

• By dividing the distance by time

• By adding the distance and time

• By subtracting the time from the distance

What is the final speed of the plane in meters per second?

• 162.6 m/s

• 5354.8 m/s

• 30,500 m/s

• 33 m/s
