#vec r#= - #68*1/2 hati##-68*sqrt3/2 hatj# + #170*cos 20 hat j#-#170*sin20*hati#

Explanation:

The resultant disp is

#vec r#= - #68*1/2 hati##-68*sqrt3/2 hatj# + #170*cos 20 hat j#-#170*sin20*hati#own #.

by talking components along #hatj# and #hat i# we did it.

solve for the answer ,or you can leave it this way as non standard angles are used.
