Answer:
(√1 - a²)
Step-by-step explanation:
cos(sin⁻¹ a) = cos x°
sin x° = sin (sin⁻¹ a) = a
as shown in the attached picture
sin x° = a/1 cos x° = (√1 - a²) / 1 = (√1 - a²)

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
