V. Find the angle measurements between the resultant vector and force vector when
two forces are applied to an object.
18. Two forces with magnitudes of 15
pounds and 10 pounds are applied to an
object. The magnitude of the resultant
is 24 pounds. Find the measurement of
the angle between the resultant vector
and the vector of the 10 pound force to
the nearest whole degree.
19. Two forces with magnitudes of 6
pounds and 18 pounds are applied to an
object. The magnitude of the resultant
is 13 pounds. Find the measurement of
the angle between the resultant vector
and the vector of the 18 pound force to
the nearest whole degree.

pounds and 62 pounds are applied to an
object. The magnitude of the resultant
is 100 pounds. Find the measurement
of the angle between the resultant
vector and the vector of the 45 pound
force to the nearest whole degree.

pounds and 340 pounds are applied to
an object. The magnitude of the
resultant is 150 pounds. Find the
measurement of the angle between the
resultant vector and the vector of the
200 pound force to the nearest whole
degree.

pounds and 42 pounds are applied to an
object. The magnitude of the resultant
is 31pounds. Find the measurement of
the angle between the resultant vector
and the vector of the 42 pound force to
the nearest whole degree.
