Dindnfdbru math jfnrjfdn

d) 15.9

Step-by-step explanation:

It's the only that makes sense like its not 8 or 4 because the line is bigger than the 11.9 one. and it's not 31.8 because the line is smaller than 19.9

and yeah math is dindnfdbru jfnrjfdn

∠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.
