What is the angle between the hands of the clock at 7:20 At 7 o’ clock, the hour hand is at 210 degrees from the vertical. Each hour on the clock represents an angle of 30 degrees (360 divided by 12). Examples: Ex.1. 15° At 5:30 the hour hand rests half way between the 5 and 6 and the minute hand exactly at 6. Following are detailed steps. Track your scores, create tests, and take your learning to the next level! If a watch or a clock indicates 8.15, when the correct time is 8, it is said to be 15 minutes too fast. So, we can calculate angle in degrees of the hour hand and minute hand separately and return their difference using below formula Degree (hr) = H* (360/12) + (M*360)/ (12*60) Degree (min) = M* (360/60) Angle between hands of a clock. I understand that delta theta is 90 degrees (i.e. 40 min. Within an clock, there are 60 total minutes. The formula to get the angle between the hour and minute hands of the clock can be shown as: Angle in degrees = (M * 6) - [(H * 30) + ((M/60)*30)] where M = the no. If the required angle is A, then A = 30*H - (11*M/2) where H= hour hand, M= Minute hand. on or linked-to by the Website infringes your copyright, you should consider first contacting an attorney. What angle is that? Goal: Find the angle measurement between the hour and the minute hands. So, 4 Divisions = 30 × 4 = 120 0 On the other hand, if it indicates 7.45, when the correct time is 8, it is said to be 15 minutes too slow. There are two approaches to this question: - If you assume the hour hand stays put and only moves every hour o'clock (which is a simplification, but a reasonable one), then the angle is 0º. First note that a clock is a circle made of 360 degrees, and that each number represents an angle and the separation between them is 360/12 = 30. Thus, the angle between them is  the degrees of the entire clcok, which is . So we are looking at 3 hours out of the 12 total hours on a clock. If it is 4:00, then the minute hand is pointing towards 12 while the hour hand points towards 4. The time is usually based on a 12-hour clock.. A method to solve such problems is to consider the rate of change of the angle … It is 4 o’clock. Since there are 12 hours on the clock, each hour mark is 30 degrees. The hour hand of a 12 -hour analogue clock turns 360° in 12 hours and the minute hand rotates through 360° in 60 minutes. A analog clock is divided up into 12 sectors, based on the numbers 1–12. A clock takes the shape of a circle, which is composed of 360 degrees. The angle between the hour hand and minute hand is = 120-110 = 10 degrees. Examples: Input: h = 12:00 m = 30.00 Output: 165 degree Input: h = 3.00 m = 30.00 Output: 75 degree a. Determine the included angle between the hands of a clock if the time of the day is given.

Special Angles between the Hour Hand and the Minute Hand of a clock. a 33: 5: minutes past 7 am: 12: b. H = Hour. With the help of the community we can continue to Angle 2 = 60°. As there are 24 half-hour intervals on a clock, the angle of one is: 360/24 = 15° As the hands are one half-hour interval apart they are 15° apart. The will be equal to the difference between the two angle measures. as Since we know that the angle covered by hour hand in one minute =0.5 0 and the hour hand covered g1 segment in 20 minutes so we can say that angle covered by sub gap g1 will be =20*0.5 0 = 10 0 . ix. Angle 2 = 360 - 300°. As the clock is divided into 12 sections, the distance between each number is equivalent to 30° (360/12). In 20 minutes, Hour hand = 210 + 20* (0.5) = … Your name, address, telephone number and email address; and Your Infringement Notice may be forwarded to the party that made the content available or to third parties such The hour hand on a clockface points to the , and the minute hand points to the . A clock shows that the time is 9:00am. To get angle of seg0 we have to find out sub gap g1 angle so let's try to use the above formula to calculate the value of sub gap g1. So knowing that a circle has in it, ____________________________________________________________. The answer indicates that the hands of a clock will make an angle of 10 between 3 and 4 o’clock at exactly 3:18:2/11 ( 3’ o clock 18 minutes and 2/11 of minutes = 2/11*60 = 10.9 seconds) A few other links to logical reasoning based concept have been given below in the table, candidates can refer to the these for any kind of assistance: The idea is to take 12:00 (h = 12, m = 0) as a reference. Step 3: Fufill your Geometry dreams! This 11/2 degrees will be useful in finding the angle between the two hands of the clock. Medium. It is 4 o’clock. Example 2: The angle between the minute hand and the hour hand of a clock when the time is 3:30 is: Solution: At 4:00, hour hand was at 90 degrees. the C. 155º. viii.

Clock Angle Problem: Given time in hh:mm format, calculate the shorter angle between hour and minute hand in an analog clock. Since at 4 : 20 the minute hand will be at 4 and the angle between them will be same as the distance covered in degree by the hour hand in 20 minutes. At 4:30 the hour hand is between 4 and 5 and it makes an angle of 4*30+30*30/60 = 120+15 = 135 deg from 12. ChillingEffects.org. There are 12 numbers on a clock that represent the hours. (i) At 4 O’ clock, the hands are 20 minutes apart. Apply the formula for finding the angle: Angle=(30h-(11/2)m( where m stands for minutes and h stands for hours) Hence, 30x11 - 11/2x35 = 330 - 192.5 = 137.5 degrees The reflex angle = 360 - 192.5 degree = 222.5 degrees. There is a shortcut formula for these kind of problems. We are looking for the larger angle, however, so we must now do . By dividing the clock into pieces, we can determine that the angle between the two hands is . But since it is 9am on the dot, we will just be using the minute hand to count the degrees. What is the angle formed by the minute hand and the hour hand at 4:45? There are 12 of them in a complete turn (360°), so each one must be 360° ÷ 12 = 30° So the angle between the hands of a clock at 1 o'clock is 30°. Well … the hour hand sweeps between the numbers 4 and 5 over an hour. Examples: Ex.1. A statement by you: (a) that you believe in good faith that the use of the content that you claim to infringe Since we know that each number on the clock is separated by 30 degrees, we can simply add 30 to 90 degrees and get 120 degrees for the angle at 4:00.
