3. in a certain wheel, there are 15 evenly spaced spokes. what is the size of the angle between any two spokes? (hint: remember there are 360° in a complete revolution.) 4. through what angle does the minute hand of a clock turn in 20 minutes? (hint: first find out what part of an hour 20 minutes is.)

3.The angle is 24°

4.120°

Step-by-step explanation:

There are 360° in a complete revolution thus for 15 equally space spokes, the angle between every spoke is given by 360° ÷ 15 =24°

In a clock, a complete revolution yields 360°. For a 20 minutes turn, the minute hand will cover (360° ÷ 12) × 4 =120°

Answers

1) 24°

2) 120°

Explanation

There are 15 spokes meaning we are going to divide one revolution by 15.

∴ 360/ 15  = 24°

The angle between any two spokes = 24°

Question 2

In an clock, the minate hand move 360° to make 60 minutes.

This means;

60 minutes ⇒ 360°

1 minute ⇒ 360/60

               ⇒ 6°

20 minutes ⇒  20 × 6°

                   ⇒  120°
