Simple,
2.) If a circle is divided into 9 parts and your are trying to find three of those parts, first find what is 1 of those parts...
In a circle there is 360°
360/9=40
That is 1 part.
For three parts it would be 40*3=120
Your answer is 120°
3.) Do the same thing here.
A circle is 360°
360/10=36
Now, for four of those parts...
36*4=144
The answer is 144°.

Answer:
The work done is 78 ft-lbs.
Step-by-step explanation:
The work W done by a force F in moving along a vector D is
In our case the displacement vector is
So the work done is
We know that the unit of force is pounds and the distance is mesuared in feet, then the work done is 78 ft-lbs.
