**drwls**, Tuesday, March 15, 2011 at 7:02amThe paralleogram method is useful if you are doing a graphic solution. Make the two vectors adjacent sides of a parallelogram, complete the other two sides, and draw a diagonal from the corner where the two vectors touch, to the opposite corner. The diagonal will be the resultant vector.

We can't draw vectors for you. For a numerical solution, add the components.

In the +x direction your resultant component is 1.7cos45 + 2.4 cos60 = 2.402. In the +y direction the resultant component is 1.7 sin45 -2.4sin60 = -0.874

Magnitude = 2.557

Direction: arctan (-0.874/2.557)

= -18.9 degrees
