Question

7) The ratio between an exterior angle and an interior angle of a regular Polygon is 1:5, find the number of side of the polygon.​

Answer 1

Step-by-step explanation:

Let, the ratio be 1x and 5x

1x° + 5x° = 180°

6x° = 180°

x° = 180°/6

x° = 30°

1x = 30°

5x = 5 × 30° = 150°

Answer 2

Step-by-step explanation:

Let the number be 1x and 5x

1x+5x=180

6x=180

x=30

1x=1×30=30

5x=5×30=150
