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°.
Answer:
There are 16 squares and 12/16 is 75 percent so 75% - green
25% - white hope this helps :)
Step-by-step explanation:
Y's minus y's and x's minus x's.
9-5= 4
8-2= 6
These are the dimensions for your rectangle. Multiply them together.
4*6= 24
Your area is 24ft^2
