Question

I need help to find x=

Answer 1

12

Explanation:

When two shapes are similar, you need to find the scale factor of two existing corresponding sides.

For example, you can do 6 and 2.

Divide:

6/2 = 3

The scale factor: 3

Now multiply 4 and the scale factor (3):

4 × 3 = 12

So, x = 12.

Hope this helped.

Answer 2

x=12

Explanation:

Since the polygons are similar, we can write a ratio to solve

red side / yellow side

4 2

--- = ---

x 6

Using cross products

4*6 = 2x

24 = 2x

Divide by 2

24/2 =2x/2

12=x
