In a triangle two angles are in a ratio of 5:3 and the difference of the angles is 30 degrees. Find out the largest angle in the triangle

One Answer on this Question

1. Let A=5x,B=3x,C not given so consider C=x
   In triangle total angle=180°
   A+B+C=180°
   5x+3x+x=180°
   9x=180°
   X=180°/9
   X=20°
   A=5(20)=100°
   B=3(20)=60°
   C=20°
   Therefore A=100° is the largest angle
   Ans: 100°
