Graded Assignment
Test: Applications of Trigonometry
Answer the following questions to practice what you’ve learned. Write your responses in the space provided and
turn the assignment in to your instructor.

1. Using satellite technology, the distance between two planes can be measured by keeping
track of the angle between them and the distance of each plane to the tracking station.

Score

Assume plane 1 is 176.27 miles away d plane 2 is 222.34 miles
away and the angle formed with the tracking station is 38.59°.
How far apart are the planes?
Answer:

Use cosine’s law, the distance is
D = (176.27^2+222.34^2-2*176.27*222.34*cos38.5...
