Q6. The largest and the second largest angles
of a triangle are in the ratio of 13: 12
respectively. The smallest angle is 20% of the
sum of the largest and the second largest
angles. What is the sum of the smallest and the
second largest angles?

Answer:
102°
Step-by-step explanation:
Sum of three angles of a triangle = 180°
Largest angle = 13x
Second largest angle = 12x
Therefore, Third angle =
=(13x+12x)×15=5x
Therefore, 13x+12x+5x−180°
=> 3=x=180°
=> x=18030=6°
Therefore, Required sum = 5x+12x
= 17x=17×6=102°
