Answer:
64 (or 63.6)
Step-by-step explanation:
You can figure out the <K by adding the first two angles (111+60) and getting 171 (subtracting that from 180 gives you a 9-degree angle for <K
Given three angles and 1 side, you can calculate the sides as follows:
k=m*sin (K) / sin (M) = 10.65
l=m*sin (L) / sin (M) = 63.60234
Since you're solving for l, the steps would be:
l=59 * sin (111) / sin (60)
l=59 * (0.934) / (0.866)
l=55.106 / 0.866
l=63.63
Hope this helps!
