    Prove that a triangle is right angled triangle

    How can I prove that the triangle ABC is a right angled triangle for any value x if the sides are AC = 12x +24, AB=13x +26 and
    BC=5x +10. Thanks.

    I have edited your question. The answer can be obtained by using Pythogorus theorem.

    Try to show that AC^2 + BC ^2 = AB ^2.
