Answer:

Mouse makes 3 revolution .6 straight angles and 12 right angles it covered with reference to the starting point

Step-by-step explanation:

As we know ,

1 Revolution = 360°

As the mouse ran around the clock 3 times.so it makes 3 revolution.

3 revolution = 360° × 3 =1080°

180° = 1 straight angle with reference to the starting point

1080° =(1 /180° ) × 1080°         (total angle /angle equal to 1 straight angle)

          =6 straight angle with reference to the starting point.

90° = 1 right angle with reference to the starting point

1080° = (1 / 90° ) × 1080° (total angle  /angle equal to 1 right angle )

           =12 right angle with reference to the starting point
