Question

The obtuse angel between the hands of a clock at 2.30am is ...A.240° B. 105°C.120° D135°​

Answer 1

The answer is B. 105°.

Explanation:

The obtuse angle between the hands of a clock at 2:30am is 105 degrees.

To calculate the angle between the hands of a clock, we can use the formula:

angle = | (30 x H) - (11/2) x M) |

where H represents the hour and M represents the minute.

For 2:30am, H = 2 and M = 30. Substituting these values into the formula, we get:

angle = | (30 x 2) - (11/2) x 30) | = | 60 - 165 | = 105 degrees

Therefore, the answer is B. 105°.
