A boat travels 82 km on a 160-degree course. Find the distances it travels south and east, respectively

see the attached figure to better understand the problem

step 1

Find out the East's distance (dx)

we have that

cos(20)=dx/82

dx=82*cos(20)

dx=77.05 Km

step 2

Find out the South's distance (dy)

sin(20)=dy/82

dy=82*sin(20)

dy=28.05 Km

A boat travels 82 km on a 160 degree course. Find the distances it travel south and-example-1
