To find the perimeter of a triangle, you can use the formula:
\[
\text{Perimeter} = \text{Side}_1 + \text{Side}_2 + \text{Side}_3
\]
In this case, you have:
- Side 1 = 15
- Side 2 = 10
- Side 3 = \(x\) (the unknown side)
We know that the perimeter is 40, so we can write the equation:
\[
15 + 10 + x = 40
\]
Now, simplify the equation:
\[
25 + x = 40
\]
To isolate \(x\), subtract 25 from both sides:
\[
x = 40 - 25
\]
\[
x = 15
\]
So, the equation you are looking for is:
\[
15 + 10 + x = 40
\]
And the third side \(x\) is equal to 15.
\[
