A length of a triangle cannot be negative, so we are left with the answer x=6
Answer: First option.
Step-by-step explanation:
You can idenfity in the figure that 
is formed by two secants that intersect outside of the given circle.
It is important to remember that, by definition:
Knowing this, you can set up the following equation:
Therefore, you must substitute values into the equation and then evaluate, in order to find the measure of the angle .
This is:
C because the the negative always is turned into a positive if you leave a braniest answer that would mean a lot of it helped thanks!!!
