x + 1/x =3
squaring both
x2+ 1/x2 +2 =9
x2 +1/x2 = 7
2x+3x =180
x= 36
angles
108 , 72
squaring both
x2+ 1/x2 +2 =9
x2 +1/x2 = 7
2x+3x =180
x= 36
angles
108 , 72

hyy.....
1. as we know supplementry angles is equal to 180° .... so , let the angles be 2x and 3x ...
now, 2x +3x = 180°
5x =180°
x = 36°
so, the angles are ... 2x = 2× 36 = 72 °
and other angle is , 3x = 3 ×36 = 108 °
2. x + 1/x = 3
.... by squaring both sides...
x^2 + 1 / x^2 +2 = 9
x^2 + 1/x^2 = 7.....
hope this helps..
