    If they are tangent, they are congruent meaning they have the same side.

    wait, so Tangent means they are congruent? So it also means that x = 7?

    is that \[1/3x\] or \[\frac{ 1 }{ 3 }x\]?

    no but AB has to equal to 7 by solving for x

    Since both lines are equal the function must be equal to each other.

    so what do I have to do, to find x?

    Yes. Is this what the question asked you to do? Find x?

    \[\frac{ 1 }{ 3}x+5=7\] This is how you set them equal to each other. This is like pre algebra I think.
