Step-by-step explanation:

Sum of angles in a ∆ is equal to 180°

  • 45° + 3x + 9° = 180°
  • 54° + 3x = 180°
  • 3x = 180° - 54°
  • 3x = 126°
  • x = \frac{ 126 }{ 3 }
  • x = 42°

P R O O F :-

LHS = 45° + 3x + 9°

RHS = 180°

  • 45° + 3(42) + 9°
  • 45° + 126° + 9°
  • 180°

Therefore, LHS = RHS
