Look below to view the entire question.The face of a clock is inclined at 30 degrees to the vertical. If the hour hand is in horizontal position at...

a) The clock is a circle, so the sum of the angles is 360
degrees.

The clock is divided equally in 12 equal angles.
Then, the angle between each two o'clock is 360/12 = 30
degrees.

a) Now, the inclination between the 1 o'clock and
3 o'clock is 2*30 degrees = 60 degrees.

b) The
inclination between 10 o'clock and 3 o'clock is 5*30 = 150
degrees.

c) Between the clock 4 and 5 , the
angle is 15 degree from each (4 and 5 o'clock, then the angle from (3 o'clock) is 30 +
15 = 45 degrees.
