So I'm doing this math problem and the answer we provide is supposed to be presented in the correct amount of significant digits, here's the problem:
A search and rescue helicopter locates a ship in distress at a 19 degree angle of depression. If the helicopter is flying at an altitude of 800m, find the distance between the helicopter and the ship.
The problem itself I can do fine, but for some reason the answer provided in the answer key is 2457m.
Shouldn't it be rounded to 2500? 19 degrees is 2 significant digits, right?
Thanks for any help in advance!
