Answer:
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)
