- angle=|11/2(min)-30(hrs)|
=|11/2(20)-30(8)|
=|110-240|

- Option :B this one is awsome... Just draw a completly circle for every hour it ll be 30 degree angle..

- angle=|30(h)-11/2(m)|
=|30(8)-11/2(20)|
=|240-110|

- angle in hr space=360/12=30 degree
so ,in 8 hr,8*30=240 degree
so, every 60 min it take 30 degree
so in 1 min it take 1/2 degree
in 20 min it will take 10 degree
total 240-10=230 degree
360-230=130

- angle in hr space=360/12=30 degree
so ,in 8 hr,8*30=240 degree
so, every 60 min it take 30 degree
so in 1 min it take 1/2 degree
in 20 min it will take 10 degree
total 240+10=250 degree

- 8 hr 20 min = 8 1/3 hrs. = 25/3 hrs.
Angle traced by hour hand in 12 hours = 360°
=> Angle traced by hour hand in 1 hour = 30°
Therefore, angle traced by hour hand in 25/3 hr = 25/3 * 30 = 250°
Angle traced by minute hand in 60 min = 360°
=> Angle traced by minute hand in 1 min = 6°
Therefore, angle traced by minute hand in 20 min = 6 × 20 = 120°
So, required angle = (250° - 120°) = 130°
ans:a - 6 years agoHelpfull: Yes(0) No(0)
