Question

The polygons in each pair are similar. Find the scale factor of the smaller figure to the largerfigure.

Answer 1

Answers:

7) 0.8

8) 0.833

9) 0.1667

10) 0.8

Step-by-step explanation:

To find the scale factor of the smaller figure to the larger figure we need to divide the length of the sides of the smaller figure by the length of the corresponding sides of the larger figure. So, for number 7, we get:

`\text{scale factor = }(16)/(20)=0.8`

In the same way, for number 8, we get:

`\text{scale factor = }(30)/(36)=0.833`

For number 9:

`\text{scale factor = }(6)/(16)=(3)/(18)=0.1667`

For number 10:

`\text{scale factor = }(24)/(30)=(16)/(20)=0.8`
