Answer 2

Answer:

20 degrees

Step-by-step explanation:

12 hrs = 360 deg

1 hour = 30 deg

8 hrs = 240 deg

also 40 mins = 2/3 of an hr= 20 deg

when hr hand symbolises 8:40___

it will form = 240deg + 2o deg anticlockwise= 260 deg

oR 360-260= 100 clockwise with 12

now for min hand

min hand will be at 8 symbolising 40 mins

ie making an angle of 120 deg clockwise with 12

hence hr hand makes 100 deg with 12

min hand makes 120 deg with 12

they both make = 120-100=20 deg with each other.☺
