-A toy bicycle frame is constructed from five plastic pieces.
a Calculate the length of [AC],
b Calculate the size of BAC.
c Write down the size of ACD.
d Calculate the length of [AD],
e Calculate the area of the quadrilateral ABCD.

i believe it is c.y = 9x

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
