failed

Solution Steps

Step 1: Analyze the position of angle α

Angle α is measured from the positive y-axis to the negative y-axis, clockwise. The positive y-axis represents 90° and the negative y-axis is at 270°.

Step 2: Calculate the measure of angle α

Since the angle is measured clockwise from the positive y-axis to the negative y-axis, its measure is 270°. Alternatively, since a straight line represents an angle of 180°, we can add 90° to 180° to arrive at 270°.

Final Answer

The measure of angle α is 270°.
