Finding the Angle Between Clock Hands (Class 9 Maths NBF)
The Easy Formula for the Angle Between Clock Hands
circular measure angle hour minute hand clock (very important Question for NBF).
Exercise 6.2 Question No. 8 Maths Class 9th NBF (National Book Foundation) angle between hour and minute hand of clock.
Lets check how to measure angle between hour hand and minute hand of a clock at 9’o clock.
what will be the measure of angle between the hour hand and minute hand of a Clock at half past 2. find the angle between minute hand and hour hand at quarter to 7
Q 1 Find the circular measure of angle between the hour hand and minute hand of a clock at 9 o’ Clock
Formula | 30H – 11/2 M | = | 30(3) – 11/2(0) | = | 90 – 0 | = | 90 |
90
Q 2 Find the circular measure of angle between the hour hand and minute hand of a clock at 2:30
| 30H – 11/2 M | = | 30(2) – 11/2(30) | = | 60 – 11(15) | = | 60 – 165 | = | -105 |
105
Q 3 Find the circular measure of angle between the hour hand and minute hand of a clock at 6:45
Lets apply formula first
| 30H – 11/2 M | = | 30(6) – 11/2(45) | = | 180- 495/2 | = | 180 – 247.5 | = | -67.5 |
67.5
