Find the length of the right trinagle 5, 12 and x

1 answer

To find the length of the missing side of a right triangle, we can use the Pythagorean theorem which states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

In this case, if one of the sides is 5 and the other side is 12, we can use the Pythagorean theorem to find the length of the missing side, which we'll call x.

Using the Pythagorean theorem:

x^2 = 5^2 + 12^2
x^2 = 25 + 144
x^2 = 169

Taking the square root of both sides:

x = √169

x = 13

Therefore, the length of the missing side in the right triangle is 13.
