Answer:

The question is incomplete. The complete question is attached as an image and explanation is provided below.

Step-by-step explanation:

Parallelogram Law for Vector Addition:

If a force F is to be resolved into components along two axes b and c, then start at the head of force F and construct lines parallel to the axes, eventually forming a parallelogram. The sides of this parallelogram becomes Fb and Fc

We have to find the component of force
F_(AB) and
F_(AC) exerted at point A in the diagram.

We can use law of sines as illustrated in the diagram.

To find
F_(AB)


(F_(AB))/(sin60)  =(500)/(sin75)


{F_(AB)  =(500)/(sin75)sin60


{F_(AB)  =(500)/(0.965)0.866


F_(AB)=448.7 N

To find
F_(AC)


(F_(AC))/(sin45)  =(500)/(sin75)


F_(AC)  =(500)/(sin75)sin45


F_(AC)  =(500)/(0.965)0.7071


F_(AC)=366.3 N
