Answer 1

Step-by-step explanation:

angle formed by circle= 360°

in 15 minutes= 90°

in 1 min = ?

cross multiplication:

1×90/15= 6°

similarly,

8×90/15= 48°

1 hour= 60 minutes

so 60×90/15= 360°

for hour hand:

3 hours or 180 minutes is equal to 90°

so for 1 min, 1×90/180= 1/2 or 0.5°

10 min,

10×90/180 = 5°

30 min,

30×90/180= 10°

for 2 hours,

90° in 3 hours,

2×90/3= 60°
