Question

when the time between the watch is 20 minutes past 7 the angle between the hands of the watches ​

Answer 1

Answer:

100 deg

Step-by-step explanation:

Time given: 20 past 7

Lets find angles of hands from zero point:

Min hand traveled 20 min and is on 20 min mark,

Hour hand traveled 7 hr 20 min and is just over 7 mark

Min hand = 4*360/12=120 deg

Hour hand = 7 hr 20 min *360/12=7 1/3 * 30=220 deg

So the angle between hands = 220 deg -120 deg = 100 deg

Answer is 100 deg
