#1. Let x be the measure of angles W. In which their sum of the interior angles is 360°

  • [tex] \rm \angle{T} + \angle{U} + \angle{V} + \angle{W} = 360 \degree[/tex]

- Substitute the given.

  • [tex] 100 \degree + 80 \degree + 100 \degree + x = 360 \degree[/tex]

  • [tex]280 \degree + x = 360 \degree[/tex]

  • [tex]x = 360 \degree - 280 \degree[/tex]

  • [tex]x = 80\degree[/tex]

[tex]\therefore[/tex] The measure of angle W is 80 degrees.

#2. Let x be the measure of angle D. In which their sum of the interior angles is 360°

  • [tex] \rm \angle{A} + \angle{B} + \angle{C} + \angle{D} = 360 \degree[/tex]

- Substitute the given.

  • [tex]85 \degree + 95 \degree + 120 \degree + x = 360 \degree[/tex]

  • [tex]300 \degree + x = 360 \degree[/tex]

  • [tex]x = 360 \degree - 300 \degree[/tex]

  • [tex]x = 60\degree[/tex]

[tex]\therefore[/tex] The measure of angle D is 60 degrees.
