What is the angle between two hands of a clock when the time in the clock is

(a) 9’O clock


(b) 6’O clock


(c) 7:00 PM

(a) Let draw the 9’O clock and find the angle between the lines



∴ The angle is 90°


(b) Let draw the 6’O clock and find the angle between the lines



∴ The angle is 180°


(c) Let draw the 7.00 PM and find the angle between the lines



∴ The angle is 210°
