Answer:
x = 38°
Step-by-step explanation:
see the solution in given pic
L=
[tex]\\ \sf\longmapsto 180-134=46[/tex]
M=
[tex]\\ \sf\longmapsto 180-84=96[/tex]
Now using angle sum property
[tex]\\ \sf\longmapsto x+96+46=180[/tex]
[tex]\\ \sf\longmapsto x+142=180[/tex]
[tex]\\ \sf\longmapsto x=180-142[/tex]
[tex]\\ \sf\longmapsto x=38[/tex]
