My diagram shows a triangle with sides 75 and 120 and a con-contained angle of 29° adjacent to the 75 side
by sine law:
sinØ/75 = sin29°/120
sinØ = 75sin29°/120
Once you have the second angle Ø , it is easy to find the third angle and answer your question.

so the second angle is 17.46 and the third angle is 133.54. then it travels to NortEast direction, am I correct?
