let the first angle be 1x
let the second Angle be 2x
let the third angle be 1x
angle1+amgle2+angle3=180
1x+2x+1x=180
4x=180
x=180/4
x=45
first angle is 1 x 45 equal to 45
second angle is 2 x 45 is equal to 90
third angle is 1 x 45 is equal to 45
let the second Angle be 2x
let the third angle be 1x
angle1+amgle2+angle3=180
1x+2x+1x=180
4x=180
x=180/4
x=45
first angle is 1 x 45 equal to 45
second angle is 2 x 45 is equal to 90
