Let's go through the problems in the image you uploaded. I'll walk you through the steps and solutions for each one.

### 1. **Matching Euclid’s Postulates (7)**

You are asked to match the postulates with the diagrams. Here’s a quick summary of Euclid’s postulates:
   - **P1**: A straight line can be drawn from any point to any other point.
   - **P2**: A finite straight line can be extended infinitely.
   - **P3**: A circle can be drawn with any center and radius.
   - **P4**: All right angles are equal.
   - **P5**: If two lines meet a third such that the interior angles add up to less than two right angles, the two lines will eventually meet on that side when extended.

Now, let’s match:
   - **(a)** looks like two right angles, so it’s **P4**.
   - **(b)** shows two lines with arrows, meaning they extend infinitely, so it’s **P2**.
   - **(c)** shows a circle, so it’s **P3**.
   - **(d)** has a straight line connecting two points, so it’s **P1**.
   - **(e)** shows intersecting lines, suggesting it’s **P5**.

### 2. **Find \(x\) and \(y\) in the triangle (8)**

You are given a right triangle where the hypotenuse is 33, one leg is \(x\), and the other is \(y\). The smaller triangle inside has proportional sides given by 7 and 6.

Using the property of similar triangles, the ratios between corresponding sides will be the same.

Let’s set up the proportion:
\[
\frac{x}{33} = \frac{7}{11}, \quad \frac{y}{33} = \frac{6}{11}
\]

From this, solve for \(x\) and \(y\):
\[
x = \frac{7}{11} \times 33 = 21, \quad y = \frac{6}{11} \times 33 = 18
\]

So, \(x = 21\) and \(y = 18\).

### 3. **Non-congruent Shape (9)**

You are asked to circle the shape that is not congruent to the others. The third triangle from the left looks different in shape and size, so that would be the one to circle.

### 4. **True or False: Trapezoid is a parallelogram (10)**

A trapezoid is **not** a parallelogram because it only has one pair of parallel sides, while a parallelogram requires two pairs of parallel sides. So, this statement is **False**.

### 5. **Solve the equation: (11)**

The problem asks for a number such that "five less than three times a number is 19."

Let the number be \(n\). The equation would be:
\[
3n - 5 = 19
\]

Solve for \(n\):
\[
3n = 24 \quad \Rightarrow \quad n = 8
\]

So, the number is \(8\).
