The flying drones are illustrations of the laws of cosines
Both flying drones would be 128.13 meters apart after 1 hour
<h3>How to determine the distance between them</h3>
For drone A, we have:
- Angle =120 degrees
- Speed = 80 mph
So, the distance after one hour is:
Distance = 80 m
The distance is calculated using:
Distance = Speed * Time
For drone B, we have:
- Angle = 320 degrees
- Speed = 50 mph
So, the distance after one hour is:
Distance = 50 m
The angle between them is calculated as:
This gives
Using the laws of cosine, the distance (d) between them after 1 hour is:
So, we have:
Evaluate the expression
Hence, both drones would be 128.13 meters apart after 1 hour

83.57 i believe because you would round the 43 down so it would stay the same
