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.
