When David arrived in the country of Georgia, he exchanged \$165$165dollar sign, 165 of United States (US) currency for 385385385 Georgian Laris. When he is ready to return to the US, he has 147147147 Laris left. Assuming the exchange rate is the same, how many US dollars is that worth?

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
