: A car is traveling on a track that is perpenicular to a railroad track. When the car is 30 meters from the crossing, the car's new collision detector warns the river that there is a train 50 meters from the car and heading toward the same crossing. How far is the train from the crossing? This question is from textbook

use the formula a^2+b^2=C^2
so to find b^2
b^2=c^2-A^2
B^2=50^2-30^2
B^2=1600
so b=40m
the train is 40 m from the tracks.
