The measure of the angle between the coordinate axes is (a) `0^@` (b) `90^@` (c) `180^@` (d) `360^@`

Text Solution

Verified by Experts

The measure of the angle between two coordinate axes is `90@`.This is because the angles between coordinate axes is mutually perpendicular to each other and the angle between two angles is `90@` .So,the angles between coordinate axes is `90@`.
