How to find value of y in polygon JKLM

Answer 1

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:

$4y+2y+6y+4y=360\\16y=360\\y=\frac{360}{16}=22.5$

y = 22.5
