How long can the third side of a triangle be if the other two sides are 7 cm and 16 cm, respectively?

Both of these sides can be legs or a side equal to 16 centimeters can be a hypotenuse. Let’s find the third side through the Pythagorean theorem (the sum of the squares of the legs is equal to the square of the hypotenuse).
In the first case, the third party is equal to:
7 ^ 2 + 16 ^ 2 = x ^ 2;
x = к√ (305).
In the second case, the third party is equal to:
7 ^ 2 + x ^ 2 = 16 ^ 2;
x = √ (16 ^ 2-7 ^ 2);
x = √ 207.
