" 4.) What is the angle between "vec A+vec B" and "vec A timesvec B?

What is the angle between (vec A+ vec B) and (vec A xx vec B) ?

The angle between vec(A) + vec(B) and vec(A) xx vec(B) is

Let vec(a) , vec(b) and vec(c) be three non-zero vectors such that no two of them are collinear and (vec(a)×vec(b))×vec(c)=1/3|vec(b)||vec(c)|vec(a) . If theta is the angle between vectors vec(b) and vec(c) , then the value of sintheta is:
