268.3 N a 182.3º
Explicación:
F1x = 300 * cos 40 = 229.8 F1y = 300 * sen 40 = 192.8
F2x = 400 * cos 140 = -306.4 F2y = 400 * sen 40 = 257.1
F3x = 250 * cos 220 = -191.5 F3y = 250 * sen 220 = -160.7
F4x = 300 * cos 270 = 0 F4y = 300 * sen 270 = -300
F resultante (x) = 229.8 - 306.4 - 191.5 + 0 = -268.1
F resultante (y) = 192.8 + 257.1 - 160.7 - 300 = -10.8
F resultante = √(-268.1)²+(-10.8)² = 268.3 N
arc tan (10.8 / 268.1) = 2.3º + 180º (3er cuadrante) = 182.3º
