Since the sale price is always less than the original, we take the original and subtract from it the percent off to give us the sale price. Putting that into equation form:

s = r - .10r

which says, in words, that the sale price is equal to the regular price minus 10% of the regular price.

Given that Triangle ABC ~ DEF, solve for x.

attashe74 [19]

ANSWER

Given that Δ ABC ~ ΔDEF

solve for x

To proof

as given in the question

ΔABC ~ ΔDEF

this means their sides are proportional to each other.

thus

$\frac{AB}{AC} = \frac{ED}{DF}$

As given

AB = 30unit

AC = 24unit

ED = 5unit

DF = x

put in the above

$x = \frac{5\times24}{30}$

solving

x = 4 unit

option (C) is correct

Hence proved
