Question

Circle C is shown. 2 chords intersect at a point to form 4 chord segments. The lengths of the segments are 4 and x + 3, and 12 and x minus 7.

What is the length of the longer of the two chords shown?

Answer 1

Geometrically the is the length of a diagonal across a square with sides of one unit of length; this follows the Pythagorean theorem. It was probably the first number known to be irrational.[citation needed]

As a good rational approximation for the square root of two, with a reasonably small denominator, the fraction 99/70 (≈ 1.4142857) is sometimes used.

The sequence A002193 in the OEIS consists of the digits in the decimal expansion of the square root of 2, here truncated to 65 decimal places:
