Answer: [tex]x=1[/tex]
Step-by-step explanation:
In order to find the value of "x", it is important to remember that:
[tex]Tangent\ chord\ angle=\frac{1}{2}(Intercepted\ arc)[/tex]
We can identify in the figure that:
[tex]Tangent\ chord\ angle=(43x)\°\\\\Intercepted\ arc=AB[/tex]
Then:
[tex]43x=\frac{1}{2}AB[/tex]
Solving for AB:
[tex]2(43x)=AB\\\\AB=86x[/tex]
Now, since there are 360° in a circle, we know that:
[tex]AB+(272x+2)=360[/tex]
Then we can substitute [tex]AB=86x[/tex] into [tex]AB+(272x+2)=360\°[/tex] and solve for "x". This is:
[tex](86x)+(272x+2)=360\\\\358x=360-2\\\\x=\frac{358}{358}\\\\x=1[/tex]
