(c ) starts at 5 and makes ¾ of a revolution

3. Find the number of right angles turned by the hour hand when it goes from (a)
10 to 1 (b) 5 to 11 ( c) 2 to 8

Answer 1

Explanation:

$\huge{\underline{\boxed{\bf{{★Λnswεr★}}}}}$

In complete clockwise revolution, the hard of a

clock will rotate by 360°

If the hand of the clock starts at 12 and makes 1/2 of a revolution clockwise, then it will rotate by 180° and hence, it will stop at 6.
