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.
The sequence is a geometric sequence with a common ratio of 2. since the common ratio is greater than 1, the sequence diverges.
15 tickets are yours.

You move the decimal point 2 places to the left because .6 is 60% instead of 6%
