I believe they are all equivalent
Ex.). If angles A, B, and C are all complementary to an angle that is 30 degrees, then all three would be 60 degrees (60+30=90)
Split the triangle into a 30-60-90 triangle. Since you have LM from that triangle, you can figure out the other sides. Then, using the leg from that triangle, the one next to it is a 45-45-90 triangle, meaning it's isosceles.
KM = 30 + 10√3
KL = 10√6
(sorry i'm not too sure if my "reasons" for statement/reason is correct)
