The angle between the minute hand and the hour hand of a clock when the time is 8.30, is:

Answer: Option

Explanation:

Angle traced by hour hand in | 17 | hrs = | 360 | x | 17 | ° | = 255°. | ||

2 | 12 | 2 |

Angle traced by min. hand in 30 min. = | 360 | x 30 | ° | = 180°. | ||

60 |

Required angle = (255 - 180)° = 75°.

we can do by formula also-

30 (H)-11/2(M)

= 30(8)-11/2(30),

= 240-165,

= 75.

30 (H)-11/2(M)

= 30(8)-11/2(30),

= 240-165,

= 75.

30*Hours-5.5*Minutes.

=30 * 8-5.5*30,

=240-165,

=75°.

=30 * 8-5.5*30,

=240-165,

=75°.

θ =| 11/2 M - 30H | where M = 30 and H =8.

θ = | 11/2 * 30 - 30*8 |,

θ = | 165 - 240 |,

θ = | -75|,

θ = 75°.

θ = | 11/2 * 30 - 30*8 |,

θ = | 165 - 240 |,

θ = | -75|,

θ = 75°.

To find the angle between the times 1.05,2.10,3.15,4.20,5.25, 6.30,7.35,8.40,9.45,10.50,11.55 and 12.60 only takes the half of the minutes.

For 1.05=2.50, 2.10=5 and so on.

For 1.05=2.50, 2.10=5 and so on.

Simple way to find out the degrees is 8:30

Step1: Multiply hour and min= 8 * 30 = 240.

Step:2: Now multiply 30*11/2 = 165.

Step3: Subtract 240 -165= 75° ->answer.

How is it possible as 1min = 6 degree?

=> 10 mins= 60 degree.

So, solution is wrong.

=> 10 mins= 60 degree.

So, solution is wrong.
