Given: △KLM, LM=20 3 <br> m∠L=105°, m∠M=30°<br> Find: KL and KM
Yuki888 [10]

Answer:


Step-by-step explanation:

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
