Answer:

LA = 60 LB = 106 LC=14

Explanation:

in triangle abc

LA+LB = 166°

total sum of traiangle will 180°

then LA +LB +LC =180°

As sum of angle ab is 166°

166°+LC =180°

LC=180 -166=14°

*LC =14°

LB +LC = 120

LB+14 = 120

then LB will 120 -14 =106

LB =106

Then angle A will LA +LB + LC =180

180 -(LB+LC) =LA

180 - 120 =60
