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.

Since the ratio of the angles is 7:2:1, we can write the angles as 7x, 2x, and x, for some x. Since the sum of the angles in a triangles is 180, we have 7x + 2x + x = 180. Combining the x's on the left-hand side, we have 10x = 180
