Forces of 10 pounds and 18 pounds act on each other with an angle of 151°.


Round the magnitude to 4 decimal places and the angles to one decimal place.
The magnitude of the resultant force pounds.


The resultant force has an angle of ° with the 10 pound force.

The resultant force has an angle of ° with the 18 pound force.

Be careful on this one. One of the angles could be obtuse. Also, it is best to calculate each angle separately and check by seeing if they add to 151°.
