Abc is similar to lmn. also side ab measures 5 cm , side ac measures 7 cm, and side lm measures 35 cm what is the measure of side ln?

so, converting firstly the mixed fractions to improper fractions and then "adding".

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
