Show answer and explanation

Correct answer: (C) 152

Explanation

Positive departure means east;negative latitude means south, so the line lies in the southeast quadrant. Its reduced bearing from south is $\tan^{-1}(70/130)=28.30^\circ$. Whole-circle bearing clockwise from north is $180-28.30=151.70^\circ$,closest to **152°,C**.
