Answer:
if you consider the angle with y-axis then by applying little knowledge of trigonometry you should get the component of force along x-axis as
10*sin30= 5N
but you can do this also by first calculating the angle made by force with x-axis
which will be 90–30=60(degrees)
then the component in x-axis will come out as 10*cos60=5N
but both are essentially same ;)
