The bisector of an equilateral (regular) triangle is found by the formula:
l = √3 / 2 * a,
where l is the bisector and a is the side of the triangle.
Substitute the known values into the formula and find the length of the bisector l:
l = √3 / 2 * 10√3 = 10 * (√3) ^ 2/2 = 10 * 3/2 = 30/2 = 15 (conventional units).
Answer: l = 15 conventional units.
