Solution
1. Break Down the Problem
We need to calculate the length of the hypotenuse of a 45-45-90 triangle given that each leg is 6 units long. A 45-45-90 triangle is an isosceles right triangle, where the legs are of equal length.
2. Relevant Concepts
The relationship between the legs and the hypotenuse in a 45-45-90 triangle can be described with the following formula:
3. Analysis and Detail
Given that each leg is 6 units: Calculating , we know that :
4. Verify and Summarize
Thus, the exact length of the hypotenuse is . To summarize, we have calculated that the hypotenuse of this 45-45-90 triangle, given each leg is 6 units, is approximately 8.484 units.
Final Answer
The length of the hypotenuse is units, approximately 8.484 units. However, none of the provided options (A, B, C, D) match the actual hypotenuse length.
