Calculate the third side of the triangle if one side is 400 cm the other 300 (right triangle)

In order to solve this problem, you need to find the third side of the triangle.

1) Since this is a right-angled triangle, we will use the Pythagorean theorem:

2) First, consider the case that the third side is a diagonal, then it is equal to the root of: 400 ^ 2 + 300 ^ 2 = 250,000, it is equal to 500 cm.

3) now consider the situation that the third side is a leg, then it is equal to the root of: 400 ^ 2 – 300 ^ 2 = 750,000, it is equal to 100 * √7 cm.

We get the following answer: 500 cm or 100 * √7 cm.
