Redo large heght is 10, small 7, short length is 5 solve for large length

Given the updated problem:

- The height of the larger triangle is 10.
- The height of the smaller triangle is 7.
- The base of the smaller triangle is 5.
- We need to solve for the base of the larger triangle.

### Step 1: Identify the Triangles

We have two similar right triangles:
1. **Smaller Triangle**: Height = 7, Base = 5.
2. **Larger Triangle**: Height = 10, Base = \( x \) (which we need to find).

### Step 2: Set Up the Proportion

Since the triangles are similar, the ratios of their corresponding sides are equal:

\[
\frac{\text{Height of smaller triangle}}{\text{Base of smaller triangle}} = \frac{\text{Height of larger triangle}}{\text{Base of larger triangle}}
\]

Using the given values:

\[
\frac{7}{5} = \frac{10}{x}
\]

### Step 3: Solve for \( x \)

Cross-multiply to solve for \( x \):

\[
7x = 5 \times 10
\]

Simplify:

\[
7x = 50
\]

Now, divide both sides by 7:

\[
x = \frac{50}{7} \approx 7.14
\]

### Final Answer

The base of the larger triangle is approximately \( 7.14 \) units.
