If i’m correct it’s y=2 im 99% sure
It is -25
im practically a math genuis
I believe that A and D would be the correct answer. Because both are 30,60,90 triangles and would be congruent. The other 2 triangles only have 1 angle and their side measures are at two different places meaning they cannot be congruent.
The vertex would be (-2,4)
