How to find value of y in polygon JKLM

Answer:
y = 22.5
Step-by-step explanation:
Here, the 4 angles shown are all exterior angles of the polygon.
The sum of the exterior angles of a polygon is ALWAYS 360°
So we add up the 4 angles (given in terms of y) and sum it to 360 and solve for y:
[tex]4y+2y+6y+4y=360\\16y=360\\y=\frac{360}{16}=22.5[/tex]
y = 22.5
