The image presents two triangles, \( \triangle ABE \) and \( \triangle ACD \), where it is stated that these triangles are similar. To find the value of \( x \), let's use properties of similar triangles.

**Step-by-step explanation:**

### Step 1: Identify corresponding sides
Since \( \triangle ABE \sim \triangle ACD \), the ratios of corresponding sides will be equal. The corresponding sides are:
- \( AB \) and \( AC \)
- \( BE \) and \( CD \)
- \( AE \) and \( AD \)

### Step 2: Write the proportions of corresponding sides
Using the property of similar triangles, we set up the following proportion:

\[
\frac{AB}{AC} = \frac{BE}{CD} = \frac{AE}{AD}
\]

We are given the lengths:
- \( AB = 8 \)
- \( AC = 8 + 3 = 11 \) (since \( BC = 3 \))
- \( AE = 10 \)
- \( AD = 10 + x \) (since \( ED = x \))

### Step 3: Set up the ratio for \( AE \) and \( AD \)
We will use the third ratio for this calculation:
\[
\frac{AE}{AD} = \frac{AB}{AC}
\]

Substitute the known values:
\[
\frac{10}{10 + x} = \frac{8}{11}
\]

### Step 4: Solve for \( x \)
Now, cross-multiply to solve for \( x \):
\[
10 \times 11 = 8 \times (10 + x)
\]
\[
110 = 80 + 8x
\]
\[
110 - 80 = 8x
\]
\[
30 = 8x
\]
\[
x = \frac{30}{8} = 3.75
\]

Thus, the value of \( x \) is **3.75**.
