It looks like you've uploaded an image of a set of algebra problems involving parallelograms. I see that the task is to find the value of each variable (x, y, m, n, a, p, d, z, g, h). These variables are associated with different geometric properties of the parallelograms, including angles, sides, and relationships between them.

Let’s break down each part:

1. For problem 3: We are given the angle at the vertex and another side length. Using properties of parallelograms (like opposite sides being equal and opposite angles being equal), we can solve for $x$ and $y$.

2. For problem 4: It seems that the equation involves $m$, and since it’s a parallelogram, the angles can help us find the relationship and solve for $m$.

3. For problem 5: You have the angle and the side lengths. Using the properties of the angles and sides of parallelograms, we can determine the unknowns.

4. For problem 6: We’re given side lengths and angles, which help to find relationships for variables like $p$ and $d$.

5. For problem 7: The equation involves differences and sums of side lengths or angles, which can be simplified to find the unknown variables.

6. For problem 8: Similar to the others, we have side lengths and angles to work with.

I'll solve these step by step now, starting with the basic principles. Would you like me to walk you through each solution in detail, or should I just provide the answers?
