Bearing - navigation

A ship travels 84 km on a bearing of 17° and then travels on a bearing of 107° for 135 km. Find the distance of the end of the trip from the starting point, to the nearest kilometer.

Correct answer:

x =  159 km

Step-by-step explanation:

u=(84cos17;84sin17)=(80.33;24.559) v=(135cos107;135sin107)=(39.47;129.101) x=u+v=(80.33+(39.47))2+(24.559+129.101)2=159 km
