{\large{\mathfrak{\red{\underline{\underline{Given :}}}}}}

  • Angle AOC = 6x + 30°
  • Angle COB = 4x°

{\large{\mathfrak{\blue{\underline{\underline{To Find :}}}}}}

  • Find the value of x = ?

SOLUTION :

Concept used :

Angle AOC + COB = 180°(Linear Pair)

Now,

{\leadsto{\sf{Angle \:  AOC + COB = 180°}}}

{\leadsto{\sf{6x + 30° + 4x = 180°}}}

{\leadsto{\sf{10x + 30° = 180°}}}

{\leadsto{\sf{10x = 180° - 30°}}}

{\leadsto{\sf{10x = 150°}}}

{\leadsto{\sf{X = {\cancel\frac{150}{10} }}}}

{\large{\purple{:{\mapsto{\underline{\boxed{\bf{X = 15°}}}}}}}}

So,

{\red{\underline{\purple{\underline{\red{\mathfrak{B  \: option \:  is  \: correct.}}}}}}}
