90 degrees. Looking at a clock, 12 o'clock going all the way around and back is a 360 degree spin. So 12, 3, 6, and 9 are all 1/4 of a 360 degree spin. If you divide 360 by, you would get a 90 degree turn for each of those numbers mentioned above.
Angles around a point adds up to 360°. the clock is divided into 12 parts to read time, so first we should divide 360° by 12. 360°÷12=30, difference between 6 and 9 is 3 so, next we have to multiply 30 by 3. 30×3=90 answer-90°
