F2 = 6.40N[233.4o]

A. Fx = 8.2*cos125 + 6.40*cos233.4 =

-8.519 N.

B. Fy = 8.2*sin125 + 6.40*sin233.4 =

1.579 N.

C. F^2 = -8.519^2 + 1.579^2 = 75.07

F = 8.66 N.

D. Tan Ar=Fy/Fx = 1.579/-8.519=-0.18535

Ar = -10.5o = Reference angle.

A = -10.5 + 180 = 169.5o = 10.5o Above

the negative x axis.
