Answer 1

Answer:

Is it helpful

Explanation:

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.
