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 ✌
