A right triangle has legs of lengths $6$ units and $8$ units. What is the length of the hypotenuse? If necessary, round to the nearest tenth.

• A. $9.2$ units
• B. $7$ units
• C. $10$ units
• D. $12$ units

Answer: (C)

Verified step by step guidance

1. Identify the given information: the triangle is a right triangle with legs of lengths 6 units and 8 units.
2. Recall the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse length \(c\) is equal to the sum of the squares of the legs: \(c^2 = a^2 + b^2\).
3. Substitute the given leg lengths into the formula: \(c^2 = 6^2 + 8^2\).
4. Calculate the squares of the legs: \$6^2 = 36\( and \)8^2 = 64\(, then add them: \)36 + 64$.
5. Take the square root of the sum to find the hypotenuse length: \(c = \sqrt{36 + 64}\).
