Equation:
4x\degree + 2x\degree = 180°

Answer:

120°, 60°

Explanation:

Since, sum of any two Supplementary angles is always 180°.


\therefore 4x\degree + 2x\degree = 180°\\</p><p>\therefore 6x\degree = 180°\\</p><p>\therefore 6x = 180\\\\</p><p>\therefore x = (180)/(6)\\\\</p><p>\therefore x = 30\\</p><p>\implies \\</p><p>4x° = (4* 30)° = 120°\\</p><p>\&amp;\\</p><p>2x° = (2* 30)° = 60°\\</p><p>
