# Find The Value of X Given (x,2)

[SOLVED] Find The Value of X Given (x,2)...

1. Homework Statement
In the figure above, Lines AB and BC are radii of the circle with center B. What is the value of X? (see attached)

I am lost. I don't know how to begin to solve this problem.

<ABC is a right triangle. Does that factor into the equation?

It would appear that the answer has to be a negative number.

No. You must subtract 5 from the x coordinate of the center of the circle....What does that give?

That would be 1 - 5 = -4

(-4, 2)
