then the tree triangles in the first part of the big triangle

then the first layer of the triangle itself

then 3 more triangle starting from top to bottom

what do you need me to answer?

step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
