this triangle is

Answer 1

Hope this helps You...

Answer 2

sum of all angles in triangle=180




given ratio -->

1:5:12




Let us take unknown number =1x

5x

12x


1x+5x+12x=180

18x=180

x=180/18


x=10


1x=1×10=10

5x =5×10=50



12x=12×10=120


therefore,120 is biggest angle


the angles in triangle=10,50,and120
