Answer:
B. 41.8° is the correct answer
Step-by-step explanation:
We are given that,
Length of Eduardo's flight path = 273 miles
Length of Paul's flight path = 357 miles
Distance between their destinations = 238 miles.
Now, using the law of cosines, we get,
i.e.
i.e.
i.e.
i.e.
i.e.
i.e. θ = 41.8°
Hence, the angle between their flight paths is 41.8°.
