mZIJK = 57° and mZIJL = 20° Find mLJK

Sagot :

we can write a relation

[tex]\angle IJL+\angle LJK=\angle IJK[/tex]

so, replacing

[tex]20+\angle LJK=57[/tex]

and solving for LJK

[tex]\begin{gathered} \angle LJK=57-20\cdot \\ \angle LJK=37 \end{gathered}[/tex]

the value of LJK is 37° so, the right option is C
