Answer: 130 degrees. 360x4=1440 degrees. So each time we have 360 degree rotation, we end up where we started. The rotation will be 1575-1440=130 degrees.
The effect of the rotation is the same as that of a 90 degree clockwise rotation. In matrix notation, it is equivalent to [post-]multiplication by the 2x2 matrix: { 0 1 } {-1 0 }
Short answer: 72 degrees Longer answer: To rotate a star until it looks the same you need to make 1/5 of a complete 360 degree turn (since a star has 5 points). Sice 1/5 X 360 = 72, the answer is 72 degree angle rotation.
360 degree rotation (clockwise or anticlockwise) leaves any figure in exactly the same position as it was at the start. So YOU DO NOTHING.
No. They are different units. If you're saying on the clock, no. If one degree was one hour there would be 360 hours. 360/12=30, there fore it is 30 degrees on the clock If you are speaking of the rotation of the earth, 360/24 = 15 degrees each hour.
