The angle between the minute hand and the hour hand of a clock when the time is 8.30, is:
Answer : Option B
Explanation :
Angle traced by hour hand in\(\frac { 17 } { 2 } \)hrs=[\( \frac { 360 } { 12 } \)x\(\frac { 17 } { 2 }]^0\)= 255°
Angle traced by min. hand in 30 min. =[\( \frac { 360 } { 60} \)x\(30]^o\)== 180°.
Required angle = (255 - 180)° = 75°.
