# First time Pre-Calc student, HW Help with Goose

ajo1023
Homework Statement:
On a wild goose chase, Harry the Canadian Goose flies north for the summer for 150 km then abruptly makes a 55 degree turn W of North to land on a pond. What is Harry's displacement so far on his trip home?
Relevant Equations:
I thought I understood what I was doing but after discussion with others, I'm questioning where to even start. I know I have to draw a graph but I don't know what It should looke like. I'd love some help.
150 km
tan(35)=150/x
Hyp=316.58
I know this isn't right where did I go wrong or did I even start correctly

What information do you need to make the calculation, and do you have it ?

What information do you need to make the calculation, and do you have it ?
The only information given in the problem is 150 km and a turn of 55 degrees.

You may want to draw a diagram, for yourself at least.

The question as stated seems to be missing important information. Harry goes north for 150 km, and then turns, but how far does he go after the turn? Are you sure you have included all the information given in the problem?

Your drawing that you posted is incorrect. The 55 deg. angle means 55 degrees to the west of North. The angle you show is 55 degrees west of South.

Actually...
then abruptly makes a 55 degree turn W of North
isn't terribly clear : is this goose making a 55deg left turn from its northerly heading ? or is it turning to N55W .
