The brightness of the illumination of an object varies inversely as the square of the distance from the object to the source of light. how far from the bulb does an object receive four times as much illumination as it does when it is 8 m from the bulb

∠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.

definitely a. the others have almost all data points on one side of the line.
