Given data

F1 = 300 N
u = __

v = __

Use law of cosines and law sines because only one sides and angles are known.

Figure 12 (b)

By using Parallelogram method, the angles are known

o
β = 30
o
γ = 130
o
o
o
o
α = 180 – 130 – 30 = 20

Now, applying the law of sines

sin sin sin
= =
1

sin 20 sin 130 sin 30
= =
300

sin 20
= ( ) 300 = 133.94
130

sin 30
= ( ) 300 = 195.81
130
