<h2>
Step-by-step explanation:</h2>
We have two forces as follows:
<u>First force:</u>
Magnitude: 150 pounds
Angle: 30°
<u>First force:</u>
Magnitude: 100 pounds
Angle: 120°
So the components can be found as follows:

So the components of the resultant force can be found by adding each component of the individual forces as follows:

Finally, the magnitude and direction of the resultant force is:
