Final answer:
The Pythagorean theorem is used to find the lengths of the sides of a right triangle, with the legs expressed as x and 2x + 12, and the hypotenuse as 2x + 13. Solve x² + (2x + 12)² = (2x + 13)² to find the value of x.
Step-by-step explanation:
The subject of the question is to find the lengths of the sides of a right triangle given certain expressions for their lengths. According to the Pythagorean theorem which relates the lengths of the legs of a right triangle with the hypotenuse, the equation is a² + b² = c².
In this situation, the legs are given as x and 2x + 12, and the hypotenuse is given as 2x + 13. Plugging these values into the theorem, we get:
- x² + (2x + 12)² = (2x + 13)²
By solving this equation, we can find the value of x and thus determine the exact lengths of the triangle's legs.
