Pavlova-9 [17]
  • <em>Answer:</em>

<em>x = 25</em>

  • <em>Step-by-step explanation:</em>

<em>Hi there ! </em>

  • <em><u> the opposite angles are equal</u></em>

<em><u>4x - 25 = 25 + 2x</u></em>

<em><u>4x - 2x = 25 + 25</u></em>

<em><u>2x = 50</u></em>

<em><u>x  = 50 : 2</u></em>

<em><u>x = 25</u></em>

<em><u>Good luck ! </u></em>
