Question
At 2'0 clock, the hands of a clock make an acute angle
and a reflex angle. How much is the reflex angle (in degrees)?Solution
Angle between the hour hand and minute hand = (30 H - 11 M /2) H = hour, M = minute At 2, 'o clock H = 2 M = 0 So, (30 x 2 - 11 x 0 / 2) 60 - 0 = 600 Now, Reflex angle = 3600 - 600 =3000
