Help and Mathematics maybe?

Yep, looking for my mistakes i got the following information.
1- How was i gonna put the value of vector in the equation of a circle.
2-To begin with the formula (.5.....) couldn't be applied because it's not assured that the circle is an equilateral one.
Haste makes waste :sick:

Uh I totally forgot how to cal angles. but lemme think. It is the angle between their normals. So

equation of plane OAB is z= 0

So angle cos (angle)= 1(1)/ ( Sqrt(4x4 + 2x2 + 1x1) x (1x1)) = 1/sqrt(21)

SO angle between 2 planes = cosine inverse of (1/sqrt(21))
