how to find the angles of a triangle if its ratio are given

step 1- multiply their ratios by x one by one

step 2- then add them

step 3- put x one one side and divide 180 by their coefficient.

e.g. 2:3:1= 180

2x + 3x +x =180

6x =180

x =180/6

x =30

first angle =2(30)=60

second angle=3(30)=90

third angle=1(30)=30

by this way you can find the angles of any ratio.
