Adjacent angles are angles that share common vertex and common point. Supplementary angles are angles which sum equals to 180 degree. Therefore,
The a pair of adjacent supplementary angles will be as follows
[tex]\begin{gathered} \angle\text{KJM and }\angle\text{MJN} \\ \angle\text{KJM = }90\text{ + 56 = 146 degree} \\ \angle\text{MJN = }34\text{ degree} \\ 34\text{ + 146 = 180 degree} \end{gathered}[/tex]
