Answer:
A:
Step-by-step explanation:
Side length ratios in a 30°-60°-90° "special" triangle are (shortest to longest):
1 : √3 : 2
Comparing to the given side lengths, we have ...
1 : √3 : 2 = x : 20 : y
Making these ratios the same gives ...
x = 20/√3 = (20√3)/3
y = 2x = (40√3)/3
These values match choice A.
I believe the answer would be a because its the one that doesn't change<span />
