Final answer:
To find the length of side AB, we can use the Pythagorean theorem to calculate the length of the hypotenuse. The length of side AB is 4 units.
Step-by-step explanation:
Based on the question, we are given three sides A, B, and C. To find the length of side AB, we need to use the Pythagorean theorem, which states that in a right-angled triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
Using this theorem, we can calculate the length of side AB as follows:
AB = √(A^2 + B^2) = √(4^2 + 6^2) = √52 = 4√13 units.
Therefore, the correct answer is D) 4 units.
