1.	What is the angle between `vec(A)` and `vec(B)`, if `vec(A)` and `vec(B)` are the adjacent sides of a parallelogram drawn from a common point and the area of the parallelogram is `AB//2`?
Answer» Area of paralleloogram `= \| vec A xx vec B\|` `=AB sin theta 1/2 AB (Given )` :. Sin theta =1/2 sin 30^(@)` or ` theta =30^(@)`.
