The statements about the clock are accurate are;
- The central angle measure when one hand points at 2 and the other points at 4 is 60°.
- With one hand at 5 and the other at 10, the minor arc formed by the hands is about 15.7 in.
- The length of the minor arc between 11 and 2 is the same as the length of the minor arc between 7 and 10.
Why are the statement above correct?
1. Note that the face of a clock is divided into 12 equal parts and the Angle of each part is= 30°
If one hand points at 2 and the other points at 4, then it is divided into two parts that is 2 to 3 and 3 to 4.
The angle that will be formed then will be = 2 (30) = 60°
So therefore option one is correct
111. When a person place one hand at 5 and the other hand at 10, then it is divided into 5 parts.
The angle that is formed= 30(5) = 150°.
Therefore, the arc length =(37.68) = 15.7.
So therefore, Option three is correct.
V. When the length of the minor arc ranges from 11 to 2, then this is divided is 3 parts.
So therefore, 3(30) = 90°
The minor arc is said to ranges from 7 to 10 and it is represented by 3(30) = 90°
So therefore option five is correct.
