Forces of 9 pounds and 15 pounds act on each other with an angle of 72°.
The magnitude of the resultant force
The resultant force has an angle of
pounds.
* with the 9 pound force.
The resultant force has an angle of
with the 15 pound force.
It is best to calculate each angle separately and check by seeing if they add to 72°.
