To solve for AB, we need a bit more information about the triangle. Assuming it's a right triangle, wherein:
- The hypotenuse is the longest side (the side opposite the right angle),
- The legs are the two sides that form the right angle,
we typically use the Pythagorean theorem to solve for the length of one side if the lengths of the other two sides are known.
The Pythagorean theorem states:
\[ c^2 = a^2 + b^2 \]
Where:
- \(c\) is the length of the hypotenuse,
- \(a\) and \(b\) are the lengths of the legs.
If you can provide the lengths of the sides, especially which one corresponds to AB, I can help further with the calculation. For instance, if you provide the lengths of both legs or the hypotenuse and one leg, I can solve for AB accordingly.
