Answer:
The correct answer is option D. Mathematical.
Explanation:
The Pythagorean theorem is used to find out the one side of the length of the triangle if the length of the other two sides is given or known already. The Pythagorean theorem says that in a right triangle if the longer side is C and other two sides are A and B than,
A²+B²=C²
This equation helps to find out the length of any one side if the lengths of the other two are known. The length of the longer side of a right triangle is equal to the sum of the squares of the lengths other 2 sides.
Thus, the correct answer is option D. Mathematical.
