First we will draw the angles for better understanding
To find JML we will use the supplementary angles
[tex]\begin{gathered} \text{JML}=KJ-\text{LMK} \\ \text{JML}=180º-154º \\ \text{JML}=26º \end{gathered}[/tex]To find NMK we will use the supplementary angles again becase LN=180º
[tex]\begin{gathered} LN=180º \\ \text{NMK}=LN-\text{LMK} \\ \text{NMK}=180º-154º \\ \text{NMK}=26º \end{gathered}[/tex]finally we use the complementary angles to find PMN
[tex]\begin{gathered} \text{PMN}=90º-\text{NMK} \\ \text{PMN}=64º \end{gathered}[/tex]
