Answer 1

Answer:

12 right angles

Step-by-step explanation:

because 4 right angles from 3 to 4 and 4 angles from 4 to 5 similarly 4 angles from 5 am to 6 am

Answer 2

The minute hand forms 6 right angles starting from 3 am to 6 am.

• The minute hand moves at a faster rate of 5.5 degrees a minute (As, the hour hand moves 0.5 degrees a min and the minute hand moves 6 degrees a minute).
• On calculation, each hour has 2 instances of right angle.
• Only exceptions are, in between 2 - 3, and 8 - 9, there is only one right angle each. So, in 12 hours interval, there are a total of (12 * 2) - 2 = 22 instances of right angle.
• In a day, it sums up to be 44 instances of right angle.
• So, in between 3 am to 6 am, there are 2 * 3 = 6 right angles.
