From the given figure, find angle MLN

Dear Student,
In these triangles two sides are proportional.
i.e.
MNBC=104=2.5LNAC=93.6=2.5MLAB=114.4=2.5
 
And as we know that if all the  sides of two triangles are proportional then the two triangles are similar.
i.e.  ABC ~ LMN
In two similar triangles all corresponding internal angles are equal

i.e.
A=LB=MC=NIn ABCA+B+C=180A+50+70=180A=180-120A=60So, M=50L=60N=70MLN=60

Regards.

First we have to smilar both triangles then there corresponding angles are equal ans is.50
