Answer:
The last answer choice
Step-by-step explanation:
This transformation doesn't not keep its congruent
Write the equation of the first train: x = 12t
Write the equation of the second train: y = -20t+72, assuming the train one is at the origins when t = 0.
Now solve the equation: 12t=-20t+72,
32t = 72, then t = 2.25 hours. The two train meet after 2.25 hours.
Now the equation of the <span>pigeon is like this: x = 48t.
</span>Then for t = 2.25, we get
![x=2.25\times48=108 km](https://tex.z-dn.net/?f=x%3D2.25%5Ctimes48%3D108%20km)
<span>
The Hyde has flown 108 km when the trains meet.</span>
The force of 10 pounds is made up of the horizontal components of the 8 and 5 pound forces
8 cos 30 + 5 cos 52 = 10
so your answer is 30 degrees
