Answer/Step-by-step explanation:
You take one side and use that.
since you split it in half divide the bottom number by 2.
8/2 -> 4
ok now you need to know that since there is 2 angles the same it is a
30-30-60 triangle.
and it goes x,2x, x
you have our 2 sides so then you would just place the x=
and simplify it down
so the answer would be D: X=2
