The points c, d, e and f all lie on the same line segment, in that order, such that the ratio of cd: de: efcd: de: ef is equal to 4: 5: 2.4: 5: 2. if cf=44,cf=44, find ef. ef.

126 maybe. sorry

answer: i wpould go with c

step-by-step explanation:

f(x)=4

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
