MCQ
The angle which makes a linear pair with an angle of $61^\circ $, is of:
  • A
    $29^\circ$
  • $61^\circ $
  • C
    $122^\circ $
  • D
    $119^\circ$

Answer

Correct option: B.
$61^\circ $

Let the required angle be $x^\circ .$ It is given that $x^\circ$ makes a linear pair with $61^\circ $
$\therefore  x + 61^\circ = 180^\circ [ \therefore$ sum of angles forming linear pair is $180^\circ ]$
$\Rightarrow x = 180^\circ - 61^\circ = 199^\circ $
