The measurement of the angle is 15° (if initial angle is 0°).
Turning Through One-degree Angles
An angle is said to have an angle measure of n degrees if it rotates across n one-degree angles. Since turning through one degree means making an angle of one degree, every time you take a turn of one degree, you rotate through one degree more. Thus, turning through n one-degree angles give rise to an angle of n degrees.
Measurement of the Angle
It is given that the angle has turned through 15 one-degree angles. Thus, the angle will turn through 15°.
Let us assume the initial angle to be x°.
Then, the new angle after 15 one-degree turns would be (x+15)°
If initial angle, x = 0°, the measurement of the angle formed is 15°.
