Answer»

Given:

1 degree (1°)

To prove:

1° = 60 minutes

Solution:

  • We KNOW that a degree is traditionally DIVIDED into 60 parts.
  • These parts are called minutes.
  • 1°  is an angle made by needles or hands of hour, a minute on a clock.
  • The hour NEEDLE sweeps an angle of 360° angle 24 hours that too 2 times.
  • Therefore, 1° = 2 x 360 / 12
  • Thus, 1° is equal to 60 minutes.
  • Hence proved.
