While exploring a cave, a spelunker starts at the entrance
and moves the following distances: She goes
75.0 m north, 250 m east, 125 m at an angle 30.0° north
of east, and 150 m south. Find the resultant displacement
from the cave entrance.

draw it and set it up as triangles. 125Cos30 = 108.25
then add it to that line to get 358.25
Then find the length of the opposite side of the triangle, 125sin30= 62.5 and subtract that from 150, then subtract 75.
Set it up as a triangle and then use pythagoras to find the length of the displacement line. I don't know if that made any sense but i got 358.471m
