Ответ:
Plane B was farther away from the airport when it was 22 miles from the ground because Plane B was 34.23 miles away
Step-by-step explanation:
The journey of both planes can be represented by two right angled triangles and the distance of the planes from the airport can be represented by the hypotenuse
Solution for plane A:
We have angle and side opposite to angle so we will use sine to calculate the hypotenuse:
sinθ= Opposite/hypotenuse
hypotenuse = opposite/sinθ
hypotenuse = 22/sin(44)
hypotenuse = 31.67
Plane A is 31.67 miles away from the airport
Plane B:
sinθ= Opposite/hypotenuse
hypotenuse = opposite/sinθ
hypotenuse = 22/sin(40)
hypotenuse = 34.23
It means that Plane B is 34.23 miles away from airport.
Therefore it is concluded that Plane B was farther away from the airport when it was 22 miles from the ground because Plane B was 34.23 miles away
