S. Angle between hand is of a clock
when
the time 9:45 is
show
9​

22.5 degrees

Explanation:

a shortcut formula for these kind of problems. if the required angle is A,

A = 30*H - (11*M/2)

H= hour hand, H=9

M= Minute hand, M=45

using the formula

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)
