Associative Property if Addition
All exterior angles of a regular polygon would equal 360 degrees. SO... based on that, one exterior angle would have to multiplied by whatever sum (whole number) to equal 360 degrees to find the number of sides. Here you divide 360 by one of the exterior angles, if it does not equal a whole number then it would be inaccurate.
In this case only 54 degrees would not fit into one of the exterior angles.

Answer:
LK=12
Step-by-step explanation:
From the given figure, HI=7 and LH=9, and we know that


(1)
Now, from ΔKHL, we have

and from ΔOKH,





(2)
Also, ΔIKL is similar to ΔOHL, therefore





Using equation (2), we get




Thus, the value of LK is 12.
