When two chords<span> intersect inside a circle, the product of the two segments of one </span>chord<span> equals the product of the two segments of the other chord.
</span><span>MN*NL=KN*LN
10x=4*20=80
x=8
ML=MN+NL=18
<span /></span>
The answer is 18.
Just replace the x with 2
45+5.25n>108
-45 -45
————————
5.25n > 63
Divide both sides by 5.25
n>12
