Question

HELP URGENTLY, JUST SOLVE FOR X, ALOT OF POINTS!!!​

Answer 1

x = 5

Explanation:

Δ DEF and Δ DBC are similar by the AA postulate

Then the ratios of corresponding sides are in proportion, that is

`(DC)/(DF)` =
`(BC)/(EF)` , substitute values

`(x)/(2)` =
`(4)/(1.6)` ( cross- multiply )

1.6x = 8 ( divide both sides by 1.6 )

x = 5

Answer 2

x = 5

Explanation:

CBD is an enlarged triangle of FED

where the sides are enlarged.

FE is enlarged which is 1.6 and turned to CB length which is 4

CD is a enlarged version of the length FD which is 2

therefore a equation can be made to solve x:

2 / 1.6 = x / 4

x = 5
