Answer:
Step-by-step explanation:
The side ratios of a 30°-60°-90° right triangle are ...
1 : √3 : 2 . . . . . . shortest to longest
In your triangle, they are ...
y : x : 2√5
Then y = (2√5)/2 = √5, half the longest side.
And x = y√3 = (√5)(√3) = √(5·3) = √15, sqrt(3) times the shortest side.
In summary, x = √15 and y = √5.
