How many degrees does the minute hand of a clock turn in 30 minutes?

60 mins = 1 hr → 30 mins = 30 ÷ 60 hr = ½ hr The hour hand does 1 full rotation every 12 hours → 1 hr = 1/12 full rotation → ½ hr = ½ × 1/12 rotation = 1/24 rotation in 30 mins → 360° × 1/24 = 15° → The hour hand moves 15° in 30 minutes.

Each exterior angle of a regular polygon measures 30 degrees How many sides does the polygon have?

A regular polygon has equal angles and sides. Therefore, consider 0 degrees as a starting direction. At every corner, you turn 30 degrees to the left, until you end up back where you started. A full rotation is 360 degrees. Divide by 30, and you have turned 12 times. The polygon, therefore, has 12 sides.
