An attacker shot at some students on the 2nd floor. We need your help verifying the validity of the report.
So, what happened here?
Cell #3
Cell #6
The witness said that the attacker was around 50 meters away from the school. He shot at the 2nd floor which is 20 meters high at a 45 degree angle.
Looks like the footprints here are 50 meters away from the building. That must mean the shooter was 50 meters away when he shot at the school.
Now, we just have to verify the angle the attacker shot at.
Since we know that the attacker shot at a target 20 meters high from 50 meters away, we can get the angle using Trigonometry. tan(x)=20/50 where x is the angle that the attacker shot from. That means x is equal to 22. The shooter must have shot from a 22 degree angle.
That must mean the original report from the witness was incorrect.
I didn't do anything special. It was just simple math.
Wow, thank you so much detective!
The angle in your report was incorrect. The attacker shot from a 22 degree angle, not a 45 degree angle.
