Answer #1

As the given run values are negative, both R and S will be in the second quadrant.

Using the rise and run values, we can find the angles made by R and S with the negative x-axis

for R,

for S,

The net component of the resultant in the negative x-axis is

The net component of the resultant in the positive y-axis is

Therefore, the angle made by the resultant with the negative x-axis is

Therefore, the angle made by the resultant with the positive x-axis is
