Answer:
DEH and HEJ are complementary angles for example.
Step-by-step explanation:
We need to provide any 2 angles that sum to 90deg. We can clearly see that DEH and HEJ are complementary, we can see the same for JEK and KEF.

First you have to figure out the length of the track:

r is the half of the diameter:
200ft : 2 = 100ft

= 200

≈
628,31
The athlete has to run ca. 5280ft for one mile:
5280 : 628,31≈8,4
The athlete has to run 8,4 laps
