I see that you've uploaded a photo containing several geometry-related questions. Let's address each one:

1. Problem from the top left:

• The problem involves parallel lines $PQ \parallel RS$ and angles $\angle PQT = 20^\circ$.
• You're asked to find $\angle QTS$.

Since $PQ \parallel RS$ and $\angle PQT = 20^\circ$, you can use the fact that these are alternate interior angles formed by the transversal line $QT$. Therefore, $\angle QTS = 20^\circ$.

2. Problem in the middle:

• You're asked to "Find the value of $x$" in the adjacent figure where several angles around point $B$ and point $E$ are given, each as multiples of $x$.
• The angle values provided are:
  • $5x^\circ$, $4x^\circ$, $3x^\circ$, and $2x^\circ$.

Since the angles all meet at a point, the sum of the angles around a point is $360^\circ$. So, the equation is: $5x + 4x + 3x + 2x = 360^\circ$ Solving for $x$: $14x = 360^\circ \quad \Rightarrow \quad x = \frac{360}{14} = 25.71^\circ$

3. Problem at the bottom:

• The figure shows parallel lines $PQ \parallel RS$ and you're given that $\angle MON = 25^\circ$. You are asked to find various angles in the figure.

Given that $PQ \parallel RS$ and using the properties of alternate angles, corresponding angles, and other angle relationships, we can solve for the requested angles $\angle LOM$, $\angle OLN$, etc.

Would you like further explanation or details for any of these problems? Let me know!
