## anonymous one year ago AB and BC are tangent to circle D. Find x if AB = 1/3x+5 and BC = 7. Find x.

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

4. anonymous

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

5. anonymous

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

6. anonymous

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

7. anonymous

since BC is 7

I'm going to screenshot it give me a second

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

11. anonymous

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

12. anonymous

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

13. anonymous

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

14. anonymous

yes !
