At 7:30, 45 degrees, the dial of traditional clocks and watches has 12 scales, 360 ° divided by 12 is equal to 30 degrees. That is, the degree between each two scales is 30 degrees. At 4:30, the minute hand points to the six o'clock position, and the hour hand is in the middle of four o'clock and five o'clock, so the included angle is 30 degrees + 15 degrees = 45 degrees.
