Question

Solution

Correct option is

π/6, π/3, π/2

We have,  Thus, two sides of the triangle are represented by the vectors Since is perpendicular to . Therefore, angle between the sides represented by the given vectors is a right angle.

Now,   Thus, the lengths of the sides containing the right angle of the triangle are in the ratio . So, the other two angles are π/6 and π/3.
