How to find sides of a triangle when r1,r2 and r3 are given?

Answer 1

Hey!!!

If R1, R2 & R3 is given 
then u can use a formula,

r1 +r2 + r3 = 180 degree
as a triangle have complementary angles(180)

Ex:
    If r1, r2 & r3 are in ratio of 1:3:5
then,
          let the first no be x 
      1x+3x+5x=180
      9x=180
       x=180/9
      x= 20 units
 
sides of triangle are:

 1x=1*20=20 cm
3x=3*20=60 cm
5x=5*20=100 cm
