The product of the two segments from the two chords are equal.
4(4+5)=(x-2)(x-2+x+4) or 36=(x-2)(2x+2) or x^2-x-20=0 or (x-5)(x+4)=0
So x=5.
Answer:
I believe it's <em>C</em>
Step-by-step explanation:
4 or less let it rest 5 or more go next door I think is how it goes lol
forgot to explain: 6 is more than 5 so we add one to the next place. that makes 2 + 1 which is 3 and 3 is less than 4 so we don't add to the next place.

Answer:
y = 107 z = 73 x = 73
Step-by-step explanation:
Y and 107 are the same angle 107 + 73 = 180
Starting from
take the first derivative using the power and chain rules:
Now take the second derivative:
Optionally, you can condense the second derivative a bit by factoring out 
, which gives
