Short Answer

Expert verified

The angle formed between the hands of the clock is $330 ° .$

Step by step solution

Step 1. Given information:

The time when the hands of the clock $= 120 ° .$

Step 2. Concept used:

A clock is a circle made of $360 °$ , and that each number represents an angle and the separation between them is $\frac{360}{12} = 30 °$ .

Step 3. Applying the concept:

A clock is a circle made of $360 °$ , and that each number represents an angle and the separation between them is $\frac{360}{12} = 30 °$ .

In $120 °$ separation between the numbers is $120 ° \div 30 ° = 4$

So at $8$ o’clock and $4$ o’clock minute hand is on $12$ and the hour hand is on $8$ and $4$ respectively.

Therefore, at $8$ o’clock and $4$ o’clock angle will $120 ° .$
