Angle between hands of clock when it shows the time 9:45
Answers
There is a shortcut formula for these kind of problems. If the required angle is A, then
A = 30*H - (11*M/2)
where H= hour hand, M= Minute hand.
for this problem, H= 9, M=45; using the above formula we’ll get
A = 30*9 - (11*45/2) = 270 - (495/2) = 270 - 247.5 = 22.5 degree
If you get answers in negative form, then just remove the negative sign, the rest will be your answer. Thank you.

Answer: 22.5 degree
Step-by-step explanation:
To Find : Finding angle between hands of clock when it the time is 9:45
Given : The given time is 9:45
Solution :
Let the required angle be P.
P = 30*h - (11 × m /2)
where h is the hour hand, and m is the minute hand
According to this question, h = 9 and m = 45
∴ P = 30 × 9 - (11 × 45 / 2)
= 270 - (495 / 2)
= 270 - 247.5
= 22.5°
If one gets answer in negative form, then that negative sign is just removed.
∴ The required angle between hands of clock at time 9 : 45 is 22.5° .
