OK. Take it slow and easy, one step at a time.
-- Draw a line from the center of the circle to the left end of the
horizontal chord.
(That point doesn't have an identification letter, but it's the other
end of the '10' from point 'A'.)
-- Since that line is also a radius of the circle, its length is 14.5 .
-- When you drew the line, you made a right triangle inside the circle.
The line you drew is the hypotenuse of the right triangle.
-- You know the length of the hypotenuse (14.5), and you know
the length of one leg (10). So you can calculate the length of the
other leg ... from the center to point 'A'. That leg is √(14.5² - 10²)
-- Now you know the distance from the center of the circle to point 'A'.
The length of AB is (the radius) minus (the leg that you just found).
Seem reasonable ?
I got 4 for AB. But I was working fast and sloppy. You need to check it.
A squared plus b squared equals c squared. 5 squared is 25. 2 squared is 4. 25 plus 4 is 29. The square root of 29 is 5.385. Therefore, x=5.385. The equation for this would be •square root symbol• (25+4).
