with BA = BC (because the triangle ABC is issoseles right triangle)

remember that the property of right triangle 306090, the proportion sides infront angles 306090 is 1 : sqrt(3) : 2

yes I do remember learning about that so...then it would be 73 square root of three??

AG is side infront angle 30, while AE is side infront angle 90.
so, just multiplied by 2 from side AG to get AE

AE = 2 * AG = 2 * 73 = 146
