Question

please give me answer fast ​

Answer 1

(B) First four multiples of 15 are : 15 , 30 , 45 , 60 , 75

(C)

(i) On moving from 4 to 7 :

24 hours make 360°

1 hour make 360/24 °

= 15 °

From 4 to 7 , there are 3 hours = 3*15 = 45 °

Hence , the rotated angle is 45°

(ii) From 3 to 9 = 6 hours

angle rotated = 6 * 15 = 90 °

Hence, the angle rotated is 90°
