Find the missing side length

The missing side length is 36

Step-by-step explanation:

You need to find the ratio of the dilation so if you take corresponding sides, for example, 72 and divide by 8 you get 9. So, if you multiply each side of the triangle XYZ by 9, it should get the length of the sides on triangle ABC.

4 * 9 = 36

Hope this helps! :)

36

Step-by-step explanation:

72 is 9 times 8

63 is 9 times 7

36 is 9 times 4

     another way

       63/7 = x/4

7x = 252

x =36
