To find the missing side of a right triangle when you have two sides, you can use the Pythagorean theorem, which states:
\[ a^2 + b^2 = c^2 \]
where \(c\) is the length of the hypotenuse, and \(a\) and \(b\) are the lengths of the other two sides.
From your provided numbers, let's assume:
- One side \(a = 8\)
- Hypotenuse \(c = 18\)
We need to find the missing side \(b\). Using the Pythagorean theorem:
\[ 8^2 + b^2 = 18^2 \]
Calculating the squares:
\[ 64 + b^2 = 324 \]
Now, isolate \(b^2\):
\[ b^2 = 324 - 64 \] \[ b^2 = 260 \]
Now, take the square root to find \(b\):
\[ b = \sqrt{260} \]
Calculating \( \sqrt{260} \):
\[ b \approx 16.1245 \]
Rounding to the nearest tenth:
\[ b \approx 16.1 \]
So, the missing side of the triangle is approximately 16.1.
