Ответ:
The distance apart of the two planes is either 100.45 km or 64.40 km
Step-by-step explanation:
The given parameters are;
The angle of elevation of the plane from the two radar stations are; 20° and 59°
The altitude of the plane = 30 km
The horizontal distance from each of the radar stations from the plane is given as follows;
Therefore, we have;
The distance between the two radar stations, d = The sum of their horizontal distances from the plane
Therefore;
However, when the radar stations are on the same side, we have;
The distance between the two radar stations, dₓ = The difference of their horizontal distances from the plane
The distance apart of the two planes is either 100.45 km or 64.40 km
