1.
complementary angles add up to 90
so m <C = 90 - 71 = 19

Answer:
and ![AB=6](https://tex.z-dn.net/?f=AB%3D6)
Step-by-step explanation:
Since they are similar, the length CE is a ratio of length AC, length CD is a ratio of length AB and length DE is a ratio of length BC.
![\frac{CE}{AC} =\frac{CD}{AB} =\frac{DE}{BC}](https://tex.z-dn.net/?f=%5Cfrac%7BCE%7D%7BAC%7D%20%3D%5Cfrac%7BCD%7D%7BAB%7D%20%3D%5Cfrac%7BDE%7D%7BBC%7D)
Substituting the values,
![\frac{24}{8} =\frac{18}{AB} =\frac{DE}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B24%7D%7B8%7D%20%3D%5Cfrac%7B18%7D%7BAB%7D%20%3D%5Cfrac%7BDE%7D%7B5%7D)
×![18](https://tex.z-dn.net/?f=18)
![=24AB](https://tex.z-dn.net/?f=%3D24AB)
![AB=\frac{144}{24}](https://tex.z-dn.net/?f=AB%3D%5Cfrac%7B144%7D%7B24%7D)
