Answer:
Step-by-step explanation:
If your mind works better in degrees than it does radians, as does mine, it will be beneficial to us to see what degree measure this angle is. Convert it to degrees using the fact that 180° = π:
degrees
Now that we know that, we can plot that angle in a coordinate plane. The terminal side of the angle lands in quadrant 2. To find the reference angle, we subtract 120 from 180 and get that the reference angle is 60 degrees, which is the same as π/3.
Answer:
They are 240 kilometers apart.
Step-by-step explanation:
This question can be solved using the following relation:
In which v is the velocity, d is the distance and t is the time.
An express train travels 80km/h from Ironton to Wildwood.
Here we have . So
A local train, traveling at 48km/h, takes 2 hours longer for the same trip.
This means that when
Since
Applying cross multiplication
So the distance is:
They are 240 kilometers apart.
