CHORDS AND ARCs: Find the value of x
The answer is probably 14, but I don't know how to prove it correctly, I mean by using the mathematical language. So if it will work, I can try to guess how I got this answer. So if you will draw radiuses, like I did on the screenshot, you will get 2 equal to each other triangles, but the thing is that I have no idea why they should be equal. So if the first step is right the value of x should be equal to 14, as the side below is equal to 14 too. That's it, I guess I helped you at least a little!
The value of x in the chord and arc circle figure is 8[tex]\sqrt{2}[/tex] units.
Given:
Find:
Solution:
As it is given that the radius of the circle is 9 units.
So, from here the diameter is 2*9 units = 18 units.
Now, we will draw a line from A to B, we will then Right triangle.
From the right-angled triangle we can calculate the value of x by Pythagoras Theorem, we get;
[tex]x^{2} = (18)^{2} - (14)^{2}[/tex]
[tex]x^{2} = 324 - 196[/tex]
[tex]x^{2} = 128[/tex]
[tex]x = \sqrt{128} = 8\sqrt{2}[/tex]
Hence, the value of x is 8[tex]\sqrt{2}[/tex] units.
