Math Problem Statement

Polygon B is a scaled copy of polygon A. What is the value of c?

Solution

This problem involves scale factors, as Polygon B is a scaled-down version of Polygon A. To solve for cc, we use the fact that corresponding sides of similar polygons are proportional.

We know the following sides:

  • Polygon A: height = 35, width = 15
  • Polygon B: height = 8, width = 6

The scale factor between the polygons can be calculated by comparing the corresponding sides. Let's use the widths to calculate the scale factor:

Scale factor=Width of Polygon BWidth of Polygon A=615=25\text{Scale factor} = \frac{\text{Width of Polygon B}}{\text{Width of Polygon A}} = \frac{6}{15} = \frac{2}{5}

Now, apply this scale factor to find cc, the corresponding side in Polygon B, using the side length of 35 from Polygon A:

c=Scale factor×Height of Polygon A=25×35=14c = \text{Scale factor} \times \text{Height of Polygon A} = \frac{2}{5} \times 35 = 14

Thus, c=14c = 14.
