Answer:

The magnitude of Resultant force is F = 7.21-lbs

Explanation:

Two forces acting on an object which are named as F1 and F2.

The angle formed by the forces are 60-degrees

F1 = 6-lbs , F2 = 8-lbs

theeta = 60°

F = √F1²+F2²-2(F1)(F2)cos(theeta)

F = √(6)²+(8)²-2(6)(8)cos(60)

F = √36+64-(96)cos(60)

F = 7.21-lbs

where,

F1 = magnitude of force 1

F2 = magnitude of force 2

theeta = angle formed by forces
