Question

Guys please help questions 7-8-9-10 are also on my page please!!

Answer 1

Explanation:

4.since two sides are congruent and two angles are equal so they are similar and we can say:

`(14)/(42) = (7)/(x) \\ x = 21`

DF is 21

5.since two sides are congruent and two angles are equal so they are similar and we can say:

`(6)/(9) = (10)/(x) \\ x = 15`

EF is 15

6.

`since \: \: (4)/(20) = (6)/(30) \: \: so \: we \: can \: say \: they \: are \: similar \: so \: we \: have \\ \\ (4)/(20) = (5)/(x) \\ \\ x = 25`

DF is 25
