Find the value of x

_

The answer to your question is x = 16

Step-by-step explanation:

Use proportions to solve this problem

Process

1.- We know that the sides have the same measure, so we compare the small triangle with the big triangle

                     (x + 3) / 38 = y/ 2y

y means the length of the side with two lines.

2.- Simplification

                    (x + 3) / 38 = 1/2

3.- Solve for x

                    x + 3 = 38/2

                    x + 3 = 19

                    x = 19 - 3

4.- Result

                    x = 16
