Answer:


\sf (\pi)/(2)

Explanation:

Angles are measured in a counterclockwise direction from the positive x-axis (initial side).

Therefore, if an angle's terminal side is on the positive y-axis, the angle will be 90° or
\sf (\pi)/(2) radians.

See attached diagram for visual explanation.

If the angle was
\pi then the terminal side would be on the negative x-axis.

If the angle was
\frac32\pi then the terminal side would be on the negative y-axis.

If the angle was
2\pi then the terminal side would be on the positive x-axis and the angle would be one complete revolution of the circle.
