Answer:
The correct options are A and E.
Step-by-step explanation:
Triangle 30-60-90 means its a right angles triangle having interior angles 30, 60 and 90.
Let the shorter side be x.



It means hypotenuse is twice long as the shorter leg. Option E is correct.




It means the longer leg is √3 times as long as the shorter leg. Option A is correct.
Shorter leg = x
Longer leg =x√3
Hypotenuse = 2x
Therefore options A and E are correct.
