Problema Solution

Find the value of x. A right triangle has the length of 13 on one side and 12 on one side what is the length of the third side(x).

Answer provided by our tutors

Assume that we know the legs of the right triangle a = 12 and b = 13 and we need to find the hypotenuse x (the third side)


using Pythagorean Theorem


a^2 + b^2 = x^2


x = (a^2 + b^2)^0.5


x = (12^2 + 13^2)^0.5


by solving we find


x = 17.69 is the third side

Assume that we know one side and the hypotenuse a = 12 and c = 13 and we need to find the third side


using Pythagorean Theorem


x^2 = c^2 - a^2


x^2 = 13^2 - 12^2


by solving we find


x = 5 is the third side
