Answer:
C. 5/3 (5 sqrt 3) (8.66...)
Explanation:
You would use the SohCahToa to find out side x.
First, label your sides (10 is hypotenuse, x is the opposite, and blank side is the adjacent).
Second, figure out which part you have to use (Sin, Cosine, or Tangent). A good way to tell is of you have the missing side on top of the fraction, makes things easier.
Third, once you figure that out then plug stuff in...
Sin(theta) = O/H
Sin(60) = X/10
10sin(60) = X
8.66... = X
It’s the amount I have this in my notes lemme look for it pls
The rate of each train of the northbound train traveled 10 miles per hour faster than the southbound train 26 miles per hour.
<h3>what is speed?</h3>
Speed is the time rate at which an object is moving along a path
Let the speed of southbound train is x miles/hour
so, northbound train has speed of x+10 miles/hour.
then, Speed of both train = Total distance/ total time
(x+10+x)=210/5
2x+10= 210/5
2x+10= 42
2x= 32
x= 16 miles per hour (southbound train)
northbound train: 16+10=26 miles per hour
