To find the length of the missing leg in a right triangle, you can use the Pythagorean theorem, which states:
\[ a^2 + b^2 = c^2 \]
where \( a \) and \( b \) are the lengths of the legs, and \( c \) is the length of the hypotenuse.
If you have one leg (let's say \( a \)) and the hypotenuse (\( c \)), you can rearrange the formula to find the missing leg (\( b \)):
\[ b^2 = c^2 - a^2 \]
Then take the square root:
\[ b = \sqrt{c^2 - a^2} \]
If you provide values for either leg or the hypotenuse, I can help you calculate the length of the missing leg.
