Answer:
Explanation:
In the given figure, the triangle ABC is a right triangle with a right angle at C. We need to find the length of the side AB.
Using the Pythagorean theorem, we know that in a right triangle with sides of length a, b, and c (where c is the hypotenuse), we have c^2 = a^2 + b^2.
In this case, we have AC = 4 and BC = 3. So, applying the Pythagorean theorem, we get:
AB^2 = AC^2 + BC^2
AB^2 = 4^2 + 3^2
AB^2 = 16 + 9
AB^2 = 25
Therefore, AB = 5.
