Answer 1

Answer:

okkkkkkkkkkkkkkkkkkkk

Answer 2

Answer:

We know that, measure of complete angle of clock is 360o.

From the figure, we can say that angle at 2 = (9/12) × 360o= 270o

Then, angle at 1 = 360o – 270o

= 90o

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