Question

The angle in degree measure between two radius of a clock at 8:30 p.m is ?

Answer 1

Answer:The hour hand on a clock moves 360/12 = 30 degrees per hour.So at half past any hour, including at 8:30, the hour hand has moved 1/2*30 = 15 degrees from the position at that hour, or at 8 o'clock. The minute hand is at the digit six. If the hour hand were at the digit 8, the angle would be 360/12*2 = 60 degrees.
