Question

the reflex angle between the hands of the clock at 9:30 is :
a). 120°
b). 255°
c). 270°
d). 240°​

Answer 1

Answer:

c-270

this is correct answer believe me

Answer 2

Answer:

b). 255°

At 9:30 the minute hand is at 6 and it makes an angle of 30*6 = 180 deg from 12.

At 9:30 the hour hand is between 9 and 10 and it makes an angle of 9*30+30*30/60 = 270 + 15 = 285 deg from 12.

At 9:30 the minute and the hour hands make an angle of 285–180 = 105 deg (obtuse) and 255 deg (reflex) between them.
