Answer:

Yes, it is possible that the triangles ABC and DEF are similar. To check if two triangles are similar, one must check if all the corresponding angles are equal. To do this, we need to find the measure of triangle ABC's interior angles. We can use the Triangle Sum Theorem, which states that the sum of any triangle's three interior angles is equal to 180 degrees. So, if we subtract 22 + (2X) + 55 from 180, we get 180 - 77 = 103. Therefore, triangle ABC's interior angle measures are 22, (2X), and 103.

To determine if the two triangles are similar, we must also find the interior angle measures of triangle DEF. We can do this by subtracting 11 + 5 + (5.5X) from 180, which gives us 180 - 16.5 = 163.5. Therefore, triangle DEF's interior angle measures are 11, 5, and 163.5.

Now, since all the pairs of corresponding angles are equal (22 and 11; 2X and 5; and 103 and 163.5), the triangles ABC and DEF do have the possibility of being similar.

The value of x that makes the triangles similar is 5.

Two triangles are similar if their corresponding angles are congruent and the corresponding side lengths are proportional.

In this case, let's compare the ratios of the corresponding side lengths.

For triangle AABC, the side lengths are 22, 2x, and 55.

For triangle ADEF, the side lengths are 11, 5, and 5.5x.

Let's set up the proportions:

(22/11) = (2x/5) = (55/5.5x)

Simplifying the proportions, we get:

x = 5

Therefore, the value of x that makes the triangles similar is 5.
