Answer:
Explanation:
The ratios of side lengths in the given triangle are ...
1 : √3 : 2 = shortest : middle length : longest
We can make the longest side match the given value if we multiply these numbers by 4√5
y : x : 8√5 = 1(4√5) : √3(4√5) : 2(4√5) = 4√5 : 4√15 : 8√5
Then we have ...
x = 4√15
y = 4√5
