reaction of structure

Question

all is this sturcture stable ? or structural determinate ?

Let the top support as A , bottom support as B ,
By taking moment about A, i managed to get 10(4*4)/2 -HA(2) = 0 , HA = 40kN,
HA = HB  = 40kN ,
By taking moment about C , i managed to get -10(4*4/2) + 4(VB + VA) -40(2) = 0
VA + VB = 40kN , however , i still not able to get the exact value of VA and VB, where did i miss out ?

The beam ac is a simply supported beam with uniformly distributed load of 40N so the reactions are
$$V_B=V_C=40/2rightarrow V_B=20N$$
$$Sigma V=40, V_A=20N$$
