M is in minutes. 5:15? We can calculate where the hour hand will be at 8:00. Varsity Tutors. The idea is to take 12:00 (h = 12, m = 0) as a reference. We would also consider the angle between the hands of the clock going counter-clockwise. Calculate the angle between hour hand and minute hand This problem is know as Clock angle problem where we need to find angle between hands of an analog clock at. At , the hour hand is on the and the minute hand is at the . The will be equal to the difference between the two angle measures. Angle traced by minute hand in 60 min. So knowing that a circle has in it, ____________________________________________________________. The total measure of the angle, therefore, is 35°. So, 4 Divisions = 30 × 4 = 120 0 What is the angle formed by the minute hand and the hour hand at 4:45? The idea is to consider the rate of change of the angle in degrees per minute. At , what angle is between the hour and minute hand on a clock? We are looking for the larger angle, however, so we must now do . If the hour hand is directly on the 10, and the minute hand is on the 2, that means there are 4 sectors of 30 degrees between then, thus they are 120 degrees apart (30 * 4 = 120). If the required angle is A, then A = 30*H - (11*M/2) where H= hour hand, M= Minute hand. Since, minute hand, in 60 minutes covers 360 degree. Find the angle between both the needles of a clock. That is, the hands are three and one-third number positions apart. However, you must take into account that in the half hour that has passed from 3:00 to 3:30, the hour hand has moved half the distance between the 3 and 4. Ans: 100deg.
