Sue and Jenny kick a soccer ball at exactly the same time.Sue's foot exerts a force of 62.3 N to the north. Jenny's foot exerts a force of 115.9 N to the east. What is the magnitude of the resultant force on the ball? Answer in N.

What is the direction of the resultant force (measured from the east)? Answer in degrees

This is what i did, but im not sure if my method is correct.:

squareroot of 62.3^2 + 115.9^2=131.6N

tan^-1 62.3/115.9=28.25 degrees

my degrees were right, but is what i did to find the magnitude of the force on the ball right?
