Two forces of magnitude 12n and 8n are acting at a point. if the angle between the two forces is 60 degrees. determine the magnitude of the external force

Explanation:

We need to make an sketch of the two forces acting over the point A, and then we analyze the forces in each of the components x and y.

Therefore, finding the resulting force using Pythagoras ' theorem and the angle of the force with respect to the horizontal.

In the attached image we can find the sketch with the equations used to find the resultant force and the angle.
