Final answer:
To find the length of the missing side of a right triangle with one leg of 11 and hypotenuse of 15, apply the Pythagorean theorem. Subtract 121 from 225 and take the square root of the result, which gives the missing side length as √104, option b).
Step-by-step explanation:
The question involves finding the length of the missing side in a right triangle using the Pythagorean theorem which is given by the equation a² + b² = c², where a and b are the lengths of the legs of the triangle, and c is the length of the hypotenuse.
In this case, we know one leg (a) is 11 units, and the hypotenuse (c) is 15 units, and we are looking to find the length of the other leg (b). Plugging these values into the Pythagorean theorem, we get:
11² + b² = 15²
Which simplifies to:
121 + b² = 225
Subtract 121 from both sides to solve for b²:
b² = 225 - 121
b² = 104
Take the square root of both sides:
b = √104
Therefore, the length of the missing side b is √104, which corresponds to option b).
