Answer:

Step-by-step explanation:

The formula for the magnitude of this resultant vector, which is in Q1, btw, is:


B_(mag)=√(6.18^2+4.43^2) which gives us, to 3 sig fig's:

7.60 m. Since the resultant vector is in Q1, we don't need to add anything to the angle once we find it to 3 sig fig:


tan^(-1)((4.43)/(6.18)) gives us an angle of 35.6 degrees
