Answer:
$6
Step-by-step explanation:

180/3x then you get you answer
Answer:
13
Step-by-step explanation:
As x and y are perpendicular - we can use pythagoras.
So, The length of side x squared + The length of side y squared = The missing length squared.
12^2=144
5^2=25
144+25=169
sqrt169=13
If two chords intersect in a circle, then the products of the measures of the segments of the chords are equal.
I'm assuming that number up top is an 8. It's kind of blurry.
Since ten is a chord, and x is a segment of it, it can be expressed as x and 10 - x.
3(8) = x(10 - x)


(x - 6)(x - 4) = 0
x - 6 = 0 .... x - 4 = 0
x = 6 .... x = 4
4 or 6
