You can put this solution on YOUR website! 1. Find the angles formed by the clock @
:
One way is to find the angle of each hand in relation to 12 o'clock (0 degrees)
:
We know the hour hand moves 1/12 * 360 or 30 degrees per hr
We know the minute hand moves 360/60 or 6 degrees per min
:
a. 4:45
;
Convert the min portion to decimal hrs: 4:45 = 4.75 (45/60)
;
Find the position (in degrees) of the hr hand: 4.75 * 30 = 142.5 degrees
:
Find the position (in degrees) of the min hand: 45 * 6 = 270 degrees (obviously)
:
Find the difference: 270 - 142.5 = 127.5 degree angle formed at 4:45
:
:
b. 4:35
:
Convert the min portion to decimal hrs: 4.35 = 4.833
:
Find the position of the hr hand: 4.833 * 30 = 137.5 degrees
:
Find the position of the min hand: 35 * 6 = 210 degrees
:
Find the difference: 210 - 137.5 = 72.5 degree angle formed at 3:35
:
:
c. 11:20
:
Decimal hrs: 11:20 = 11.333
;
hr hand: 11.333 * 30 = 340 degrees
:
Min hand: 20 * 6 = 120 degrees
:
The difference: 340 - 120 = 220 degree angle formed at 11:20
or from the other side: 360 - 220 = 140 degrees
:
Did these steps help you?
