Question

2) What is the value of DE if AB = 6, AD = 8, and BC = 3?

A) 3.5
B) 4
C) 4.5
D) 5

Answer 1

B

Explanation:

Answer 2

B

Explanation:

Δ ABC and Δ ADE are similar thus the ratios of corresponding sides are equal, that is

`(DE)/(BC)` =
`(AD)/(AB)` , substitute values

`(DE)/(3)` =
`(8)/(6)` ( cross- multiply )

6DE = 24 ( divide both sides by 6 )

DE = 4 → B
