Explanation / Answer

here,

vector 1 , A = 6 * ( cos(30) i + sin(30) j) m

A = ( 5.2 i + 3 j)m

vector 2 , B = 4 * ( sin(30) i + cos(30) j)

B = ( 2 i + 3.46 j) m

the resultant , R = A + B

R = ( 7.2 m i + 6.46 m j)

|R| = sqrt(7.2^2 + 6.46^2) m

|R| = 9.7 m

theta = arctan(6.46/7.2) = 42 degree north of east
