### Geometry Problem Explanation

#### Problem Statement:
The image shows a geometric figure with points labeled as \( W, X, Y, \) and \( Z \), forming two intersecting triangles inside a quadrilateral. The following conditions and measurements are provided:

1. **Condition**: \( XY = WZ \)
2. **Angle Measurements**:
   - \( m\angle 2 = 36^\circ \)
   - \( m\angle W = 57^\circ \)
3. **Objective**: Find \( m\angle 3 \)

#### Diagram Description:
The diagram consists of two intersecting triangles within a larger quadrilateral:

- **Vertices**:
  - \(W\) on the bottom left of the diagram.
  - \(X\) on the top left of the diagram.
  - \(Y\) on the top right of the diagram.
  - \(Z\) on the bottom right of the diagram.

- **Lines and Angles**:
  - Line segments \(WX\), \(XY\), \(YZ\), and \(ZW\).
  - The quadrilateral forms two triangles \(WXY\) and \(XYZ\).
  - Angles within the quadrilateral are labeled as \(1, 2, 3,\) and \(4\).

#### Given Angles:
- \( m\angle 2 = 36^\circ \)
- \( m\angle W = 57^\circ \)

#### Task:
Find the measure of \( \angle 3 \).

#### Solution Steps:
To find \( m\angle 3 \), follow these logical steps of reasoning involving triangle properties and exterior angles:

1. **Triangle \( WXY \)**:
   - Using the given \( m\angle W = 57^\circ \) and \( m\angle 2 = 36^\circ \).

2. **Triangle Angle Sum Property**:
   - The sum of angles in any triangle is \( 180^\circ \).
   - Therefore, we can write the equation for \( \triangle WXY \):
     \[
     m\angle 1 + m\angle 2 + m\angle W = 180^\circ
     \]
   - Substituting the given values:
     \[
     m\angle 1 + 36^\circ + 57^\circ = 180^\circ 
     \]
     \[
     m\angle 1 =
