Please give me solutions of Try these on pg no.93
Dear Student,
Please find below the solution to the asked query:
We know : Hour hand makes total angle in one revolution ( In 12 hour ) = 360 , So
Hour hand makes angle in 1 hour = = 30
1 ) As hour hand move from 5 to 12 , so that cover total hours = 12 - 5 = 7
Then,
Hour hand makes angle in 7 hour = 7 30 = 210
We know : One right angle = 90
And we can see that : 210 > 90
So,
Yes, Revolution of the hour hand more than 1 right angle .
2 ) As hour hand move from 5 to 7, so that cover total hours = 7 - 5 = 2
Then,
Hour hand makes angle in 2 hour = 2 30 = 60 ( Ans )
We know : One right angle = 90
And we can see that : 60 < 90
So,
Angle does not moved more than 1 right angle .
Hope this information will clear your doubts about topic.
