square ABCD with diagonals DB and AC intersecting at E
DC = 8radical 3
Find: DB
simplest radical form DB =
approximation DB =
In triangle BCD BD^2= BC^2+BD^2 ( pythagoras theorem)
BD^2 = (8sqrt(3))^2 + (8sqrt(3))^2
= 2 * (8sqrt(3))^2
= 2 *64*3
= 384
BD = sqrt(384)
= sqrt(8*8*6)
=+8+sqrt%286%29
=8*2.449
