What is a obtuse angle on a clock?
The obtuse angle lies between 90° and 180° and looks like a reclined chair, an angle below the staircase, or an angle formed between a minute and an hour hand of a clock at 10:15 AM.
How do you make an obtuse angle in a clock?
Reflex angle = 210° and Obtuse angle = 150°
- Step-by-step explanation:
- Total degree of one revolution = 360°
- ∴ Each division = = 30°
- ∴ Reflex angle = 7 divisions = 7 × 30° = 210°
- Also,
- Obtuse angle = (12 – 7) divisions = 5 × 30° = 150°
- Hence, At 7’o clock Reflex angle = 210° and Obtuse angle = 150°
Is 5 o’clock an obtuse angle?
Hence, for each hour, the clock takes for 5 minutes and rotates constantly. It takes place in out of date and known for measuring of acute angle between the hour and when both takes by minute and hour hands point towards 12. It is making at angle of 0 degree and other index has angle 360-150=210 degrees.
What degree is 5 o clock?
As the hour stands divide the clock into 12 slices or 12 pies or 12 sectors. Thus each sector takes 30∘. Now when the time is 5 o’clock, there are five sectors between the minute hand and the hour hand. ∴The angle between the minute hand and the hour hand at 5 o’clock is 150∘.
Which angle is obtuse?
90 degrees
Obtuse angles measure more than 90 degrees.
What angle is 1 o clock?
So the angle between the hands of a clock at 1 o’clock is 30° . Note: It doesn’t matter whether we are talking about 1 am or 1 pm, the answer is exactly the same for both. The angle between the hands at 1 o’clock could also be given as the reflex angle 330°, but we will always give the smaller (acute or obtuse) angle.
How do you write an obtuse angle?
An obtuse angle is a type of angle that is always larger than 90° but less than 180°. In other words, it lies between 90° and 180°. In the given figure, ∠XYZ shows an obtuse angle. Here, in Fig: 01, ∠DOQ forms an obtuse angle.
What is the angle between the hands of a clock at 1 o’clock?
At 1 o’clock the minute hand (red) points to the 12 and the hour hand (blue) points to the 1. So we need to find the angle between the 12 and the 1. How many of this angle are there in a complete turn? 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° .
Which is the zero degree point on the clock?
Call the “12” point on the clock the zero-degree point. At 4:45, the minute hand is at the “9” – that is, at the mark. The hour hand is three-fourths of the way from the “4” to the “5; that is, , the desired measure.
How is the angle of the hour hand calculated?
One has to account, however, for the 10 minutes that have passed. 10 minutes is 1/6 of an hour so the hour hand has also moved 1/6 of the distance between the 3 and the 4, which adds 5° (1/6 of 30°). The total measure of the angle, therefore, is 35°.
How many degrees does a clock have on it?
A clock is a circle, and a circle always contains 360 degrees. Since there are 60 minutes on a clock, each minute mark is 6 degrees. The minute hand on the clock will point at 15 minutes, allowing us to calculate it’s position on the circle.
