break this problem down to horizontal (x) and vertical (y) components! it'll probably help if you drew the problem out!
horizontal:
(10cos20) meters
20 meters
add the horizontal components together
vertical:
(10sin20) meters
perform Pythagorean theorem-
total displacement: sqrt[(horizontal)^2+(vertical)^2]
remember displacement is a vector so it also has direction! to find direction: tan^-1(vertical/horizontal)
opps! I forgot to put a negative in front of -20 meters under the horizontal component.
