Answer 1

x = 4

Explanation:

assuming you require to find the value of x

Δ ADE and Δ ACB are similar ( by the AA postulate )

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

`(AD)/(AC)` =
`(AE)/(AB)` ( substitute values )

`(x)/(x+x-2)` =
`(x+2)/(x+2+x -1)`

`(x)/(2x-2)` =
`(x+2)/(2x+1)` ( cross- multiply )

(2x - 2)(x + 2) = x(2x + 1) ← expand left side using FOIL

2x² + 2x - 4 = 2x² + x ( subtract 2x² + x from both sides )

x - 4 = 0 ( add 4 to both sides )

x = 4
