Given: MG ≅ CG, AG – 2y – 1, IC = y + 5
Questions:
• What is the value of y?
• How did you solve for y?
• How long are MG and CG? Why?

Option D

Plane B because it was 9.33 miles away

Step-by-step explanation:

This problem can be simulated by two right triangles:

For Plane A, we have the elevation angle . We know that the height is 6 miles.

To find the horizontal distance we use the function

By definition:

In this case:

hypotenuse=distance from the airport

Then:

distance from the airport: 8.64 miles

For Plane B, we have the elevation angle . We know that the height is 6 miles.

To find the distance we use the function

By definition:

In this case:

Hypotenuse=distance from the airport

Then:

distance from the airport: 9.33 miles

Finally the answer is the option D.
