The image you provided shows a quadrilateral with angles labeled and some algebraic expressions next to two of the angles.

• One of the angles is labeled as $(3x - 20)^\circ$
• Another angle is labeled as $(2x + 10)^\circ$

Since this is a quadrilateral, we know that the sum of the interior angles must be $360^\circ$. However, based on the partial information given, I would need to know the other two angles (if they are mentioned or assumed) or any additional relationships between the angles to proceed.

Could you confirm the type of quadrilateral or provide more details about the missing angles? This will help in solving for $x$.
