The first written evidence that has been found of people finding the value of pi is in an Egyptian papyrus and Babylonian tablets about 1900 BC, however, some historians believe that the ratio of the perimeter to height of pyramids built in Egypt as early as 2613 - 2589 BC suggests that Egyptians already had made approximations of the value of pi at that time.
Not enough information has been given to find the tangent BC but it will be perpendicular or at right angles to the radius of the circle.

The ancient Babylonians from around 1700 BC used pi = 3.125. The name of the person who calculated that value was not recorded.
Archimedes of Syracuse is said to be the first mathematician to make a systematic attempt to estimate pi in the third century BC.
let abc be the triangle with base bc. Consider it is equilateral triangle.. Now draw ad perpendicular to bc. Now ad equalls dc. Now tan 60 degree equalls ad/dc. With value of tan 60 and ad we can find dc. There fore bc equalls 2 * dc

No one has ever discovered the real value of pi because it is an irrational number which means it can not be expressed as a fraction and only an approximation was given to it.
Assuming that AB and AC are straight lines, the answer depends on the angle between AB and AC. Depending on that, BC can have any value in the range (22, 46).
