Plane A because it was 7.62 miles away.

Step-by-step explanation:

In the case of plane A we have a right triangle with an angle of 41 degrees and the opposite side  = 5.

The distance of the planes from the airport is the hypotenuse of the triangles.

sin 41 = opposite / hypotenuse

sin 41 = 5 / h       where h is the distance of the plane from the airport so

y = 5 / sin 41 = 7.62 miles.

By a similar process for Plane B  we see that sin 43 = 5/h

h = 5 / sin 43 = 7.33 miles.
