Question

The angle between x-axis and y-axis in a cartesian plane is:

• A. ${45}^{\circ }$
• B. ${30}^{\circ }$
• C. ${90}^{\circ }$
• D. ${60}^{\circ }$

Answer 1

The correct option is C ${90}^{\circ }$

The x-axis and y-axis in a cartesian plane is mutually perpendicular to each other.
Hence, angle between them is equal to ${90}^{\circ }.$
