Question

9:15 in clock makes which angle?​

Answer 1

Step-by-step explanation:

Again, the two angles created by the hour hand and minute hand at nine-fifteen are 172.5 degrees and 187.5 degrees. The angle made by the hour hand and minute hand on a clock at 9:15 is not all we have calculated. We have calculated the clock angles for every minute of the 12-hour clock.

Answer 2

The answers are 172.5° and 187.5°

GIVEN

Time- 9:15

TO FIND

Angle between 9:15

SOLUTION

The above problem can be simply solved as follows;

It is known that,

The clock is made up of 60 minutes.

The angle of the clock = 360°

Angle from hour hand to minute hand at 9:15

Angle made by 1 minute = 360/60 = 6°

Complete angle made by hour hand = 720°

Angle made by hour hand per minute = 720/60 = 0.5°

Number of time hour hand moves = 555 out of 720

Angle = 555 × 0.5 = 277.5°

Number of times minute hand has moved out = 15 out of 60 times

Angle = 15 × 6 = 90°

Angle from hour hand to minute hand at 9:15 = 360 - (277.5 - 90) = 172.5

Angle from minute hand to hour hand at 9:15

= 360 - the degrees from the hour hand to minute hand

= 360 - 172.5

=187.5°

Hence, The answers are 172.5° and 187.5°
