I read somewhere there is a direct formula to solve this question..2)
Angle between m and h hand is ( 11/2) *m – 30 * h
can this be apply here? if yes should i take the value of h =12 ..taking this I am not getting the answer..
Please suggest
You just should substitute h=0 in it, not h=12.
General formula is:
\(|\frac{11}{2}m - 30h|\)
If the result is greater than 180 degrees, subtract it from 360 to get the included angle.
The above can be derived from the fact that:
In 1 minute:
Hour hand moves 0.5 degrees,
Minute hand moves 6 degrees.
AND
In an hour:
Hour hand moves 30 degrees,
Minute hand moves 360 degrees.
Hope it's clear.
Please can anyone elaborate on when to assign positive and negative signs when opening the modulus in the general formula given above?
