Step-by-step explanation:
4.since two sides are congruent and two angles are equal so they are similar and we can say:
[tex] \frac{14}{42} = \frac{7}{x} \\ x = 21[/tex]
DF is 21
5.since two sides are congruent and two angles are equal so they are similar and we can say:
[tex] \frac{6}{9} = \frac{10}{x} \\ x = 15[/tex]
EF is 15
6.
[tex]since \: \: \frac{4}{20} = \frac{6}{30} \: \: so \: we \: can \: say \: they \: are \: similar \: so \: we \: have \\ \\ \frac{4}{20} = \frac{5}{x} \\ \\ x = 25[/tex]
DF is 25
