Chord of triangle

Webradius. In calculating the table of chords, Hipparchus began with 60 , so that the chord is equal to the radius, since we have an equilateral triangle. Thus crd(60) = 57;18 in sexagesimal or 34380in minutes. Now, for a 90 angle, the chord is equal to: R p 2 = 48620 = 81;2 (81 60 + 2 1) So crd(90) = 81;2 (in sexagesimal). WebThe principal root of both sides is the non-negative square root of both sides. Taking the square root of A^2+B^2 means adding A^2 and B^2 together then taking the square root of the sum. You only get A+B=C if you take the square root of A^2 and B^2 separately then adding it together.
