Answer:
   78.5 km
Step-by-step explanation:
Measured at the airport, the angle between the two planes is ...
   180° -60° -50° = 70°
The law of cosines tells us the distance between the planes is ...
   d = √(50² +80² -2·50·80·cos(70°)) ≈ √6163.84 ≈ 78.5 . . . km
The planes are about 78.5 km apart.
 
        
             
        
        
        
A, 39
You can get the average score by adding up all the total scores, (33, 41, 33, 45 and 43) and dividing that by the total number of scores, 5. 195 (total score)/5 (number of scores)= 39.
