Answer:
Given: Center of the clock face is at origin that is ( 0 , 0 )
To find : Position of the hours on the clock faces 3 o'clock , 6 o'clock , 9
o'clock and 12 o'clock.
We know that 3 o'clock on watch is on the straight right side of the center.
So, here 3 o'clock lies on right side of x-axis or positive side of x-axis.
Coordinate of 3 o'clock = ( 5 , 0 )
We know that 6 o'clock on watch is on straight bottom of the center.
So, here 6 o'clock lies on downside of y-axis or negative side of y-axis.
Coordinate of 6 o'clock = ( 0 , -5 )
We know that 9 o'clock on watch is on the straight left side of the center.
So, here 9 o'clock lies on left side of x-axis or negative side of x-axis.
Coordinate of 9 o'clock = ( -5 , 0 )
We know that 12 o'clock on watch is on the straight upside of the center.
So, here 12 o'clock lies on upside of y-axis or positive side of y-axis.
Coordinate of 12 o'clock = ( 0 , 5 )
