Answer:
Answered your other question, now I feel like I want to solve this.
So first, in this 30,60,90 triangle the relationship between the side opposite to the 90 and the 30 degrees is correct(the Hypotenuse is twice the length of the side opposite to 30 degrees).
Looks like the other side relationship is wrong though...
So see the side opposite to the 60 degree angles is supposed to be
times greater than the side opposite to the 30 degrees.
So let's find out!

Wait... ? So either you did not put the options, because none of them are wrong...
Okay you decide what to do with this.
Hope this helps!
