Three forces in the plane act on the object. Forces are 7N, 11N, and 15N. Angle between 7N and 11N forces is 105 degrees, between 11N and 15N forces is 147 degrees, and between 15 N and 7 N forces is 108 degrees.
a) Are vectors in equilibrium?
b) If not, determine magnitude and direction of resultant force.
