The equilibrant is equal and in opposite direction to the resulatant.
equilibrant= - resultant
equilibrant= - resultant

All angles are measured CCW from +x-axis.
a. Fr = 10[60o] + 15[0o].
Fr = (10*Cos60+15*Cos0) + (10*sin60+15*sin0)i.
Fr = (5+15) + (8.66+0)i = 20 + 8.66i = 21.8N.[23.4o].
b. Fe = -21.8[23.4o] = 21.8[23.4+180] = 21.8N.[203.4o]
