Question

PLEASE HELPPPPPP!!!!!!!!!!!

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.)

Answer 1

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°

Answer 2

3.The angle is 24°

4.120°

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°
