Step-by-step solution

To solve this problem, we will use the Pythagorean Theorem. It states that for a right triangle with sides a a and b b , and hypotenuse c c , the relationship is given by:

a2+b2=c2 a^2 + b^2 = c^2

In triangle ABC, let AB=a=6 AB = a = 6 and BC=b=5 BC = b = 5 . We need to find the length of the hypotenuse AC=c AC = c .

Applying the Pythagorean Theorem, we have:

62+52=c2 6^2 + 5^2 = c^2

36+25=c2 36 + 25 = c^2

61=c2 61 = c^2

To find c c , we take the square root of both sides:

c=61 c = \sqrt{61}

Thus, the length of AC is 61 \sqrt{61} .
