here's the solution for question 14:

The formula for the size of each exterior angle of a regular polygon with nn sides is 360∘n\frac{360^\circ}{n}.

Part a· 2 steps

For a regular polygon with 14 sides

  1. Apply the formula for the exterior angle.

    Exterior angle=360∘n\text{Exterior angle} = \frac{360^\circ}{n}

    Substitute n=14n=14:

    Exterior angle=360∘14\text{Exterior angle} = \frac{360^\circ}{14}
  2. Calculate the value.

    Exterior angle=180∘7≈25.714∘\text{Exterior angle} = \frac{180^\circ}{7} \approx 25.714^\circ Exterior angle≈25.71∘ (to 2 decimal places)\boxed{\text{Exterior angle} \approx 25.71^\circ \text{ (to 2 decimal places)}}

Part b

Exterior angle=15∘\text{Exterior angle} = 15^\circ

For a regular polygon with 24 sides

  1. Apply the formula for the exterior angle.

    Exterior angle=360∘n\text{Exterior angle} = \frac{360^\circ}{n}

    Substitute n=24n=24:

    Exterior angle=360∘24\text{Exterior angle} = \frac{360^\circ}{24}
  2. Calculate the value.

    Exterior angle=15∘\text{Exterior angle} = 15^\circ Exterior angle=15∘\boxed{\text{Exterior angle} = 15^\circ}
