    The triangle is acute.

    Step-by-step explanation:

    Basically, you need to use Pythagoras Theorem.

    This is what you need to know then

    In ABC with longest side c:


    c²=a²+b² then the triangle is right.

    c²>a²+b² then the triangle is obtuse.

    So let's go Pythagoras Theorem for your triangle.

    4.2²=17.64

    6.4²=40.96

    7.6²=57.76

    57.76<17.64+40.96

    So the triangle is acute
