What is the slope of a line perpendicular to the line whose equation is 3x-3y=54

-1

Step-by-step explanation:

First, put the equation of the original line in y = mx + b form

3x - 3y = 54

-3y = -3x + 54

y = x - 18

This means the slope of the line is 1. Perpendicular lines have a opposite reciprocal slope, so the line will have a slope of -1

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
