Figure : 1

The value of an exterior angle is equal to the sum of values of two opposite interior angles.

That is :

  • [tex]40 \degree + 40\degree = 3x + 20\degree[/tex]
  • [tex]80\degree = 3x + 20\degree[/tex]
  • [tex]3x = 60\degree[/tex]
  • [tex]x = 20\degree[/tex]

Therefore, value of x is 20°

And the measure of missing angle is :

  • [tex]3x + 20\degree[/tex]
  • [tex](3 \times 20\degree) + 20\degree[/tex]
  • [tex]60\degree + 20\degree[/tex]
  • [tex]80\degree[/tex]

Figure : 2

The Value of an Exterior angle is equal to the sum of values of two opposite interior angles .

Hence,

  • [tex]v + 71\degree = 107\degree[/tex]
  • [tex]v = 36\degree[/tex]

And therefore measure of missing angle is 36°, since v was the missing angle here.
