Answer 2

To find :-

Number of the two angles between hours

minute hands of a clock at 9 o'clock .

Solution :-

→We know that a measure of the complete angle of the clock is 360 °.

⇒  (9/12) × 360°= 270°

Then,  

⇒  360°– 270°= 90°

Therefore, measures of the two angles between the hour and minute hands of a clock at 9 O’ clock are 270° and 90°.
