The lengths of the sides of a triangle are in a the extended ratio of 3: 6: 8. the triangles perimeter is 510cm. what are the lengths of the sides

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
