A ray with the starting point at the origin in the complex plane passes through the point\[\left( 2+2i \right)\]. Another ray with the same starting point passes through the point \[(2-2\sqrt{3}i).\]The angle formed by these two
A)\[105{}^\circ \]
B) \[90{}^\circ \]
C)\[75{}^\circ \]
D) \[45{}^\circ \]
Correct Answer:
A
Solution :
Obviously angle between the two rays \[=\alpha +\beta \] \[=45{}^\circ +60{}^\circ \] \[=105{}^\circ \]
