Answer:
[tex] \displaystyle m\angle JKM = 50[/tex]
Step-by-step explanation:
remember that,
if a side of a triangle expanded exterior so formed is equal to the sum of the two interior angles
so,
[tex] \displaystyle m\angle JKM = 25 + 25[/tex]
simplify addition:
[tex] \displaystyle m\angle JKM = 50[/tex]
