The angle between the minute hand and the hour hand of a clock when the time is 8.30, is:
80°
75°
60°
105°
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*Hours-5.5*Minutes.
=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°.

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.

How to find the angle when time is 7.40 using 30 * h- (11/2) * Min?

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.
