Answer:
4LA=3LB
therefore
LB=4/3LA
4LA=12LC
therefore
LC=4/12LA=1/3LA
therefore in triangleABC
LA+LB+LC=180°[angle sum property of a triangle]
LA+4/3LA+1/3LA=180°. [substituting the values of LB and LC]
therefore
3LA+4LA+LA=540°
8LA=540°
LA=67.5°
therefore
LB=4/3*67.5=90°
LC=1/3*67.5=22.5
Hope it helps

Let the angles be :- x
Therefore ,
4x + 3x + 12 x = 180
⭐ Find x and then multiply with 4,3,12 to get the answer ✌
