Final answer:
The equation a? + (334) * = 9? will find the unknown leg length of a right triangle.
Step-by-step explanation:
The correct statement about the unknown leg length of a right triangle is: The equation a? + (334) * = 9? will find the unknown leg length. The Pythagorean theorem, which relates the length of the legs (a and b) and the hypotenuse (c) of a right triangle, states that a² + b² = c². By solving this equation for c, we get c = √(a² + b²). In the given equation, a? + (334) * = 9?, we can substitute the given values in place of a, b, and c to find the unknown leg length.
