For your problem, determine how many degrees past 12:00 the hour hand has moved at 10:25 (10 hours at 30 degrees per hour, plus 25 minutes at 0.5 degrees per hour). \n" ); document.write( "The minute hand moves 6 degrees per minute (360 degrees in 60 minutes). For your problem, determine how many degrees past 12:00 the minute hand has moved at 10:25. \n" ); document.write( "Find the difference between those two angles. The problem asks for the obtuse angle (between 90 and 180 degrees); if that difference is greater than 180 degrees, then the number you want is 360 degrees minus that difference. \n" ); document.write( "You can have the pleasure of doing the calculations and finding the answer by yourself. \n" ); document.write( " \n" ); document.write( " |
