Transcribed Image Text: ### Transversals and Angle Relationships
**Transversal and Angles Diagram**
In the diagram shown:
- Two parallel horizontal lines are intersected by a transversal, forming eight angles at the points of intersection.
- The angles are labeled as follows:
- At the upper intersection: \( a \), \( b \) as corresponding angles on the horizontal line, and \( d \) as the vertically opposite angle to \( b \).
- At the lower intersection: \( e \), \( f \) as corresponding angles on the horizontal line, and \( g \) and \( h \) as related angles.
The angle relationships provided are:
- \( \angle a = 60^\circ \)
- \( \angle b = 4x - 30^\circ \)
### Analyzing Angle Relationships
1. **Corresponding Angles**: Angles formed on the same side of a transversal with two parallel lines and are equal.
- \( \angle a \) corresponds to \( \angle e \).
- \( \angle b \) corresponds to \( \angle f \).
2. **Alternate Interior Angles**: Angles formed on the opposite sides of a transversal but inside two parallel lines and are equal:
- \( \angle d \) corresponds to \( \angle f \).
- \( \angle e \) corresponds to \( \angle g \).
3. **Alternate Exterior Angles**: Angles formed on the opposite sides of a transversal but outside two parallel lines and are equal:
- \( \angle a \) corresponds to \( \angle h \).
- \( \angle b \) corresponds to \( \angle g \).
4. **Vertically Opposite Angles**: Angles directly opposite each other when two lines intersect and are always equal:
- \( \angle b \) and \( \angle d \) are vertically opposite.
- \( \angle f \) and \( \angle h \) are vertically opposite.
### Solving for \( x \)
To find \( x \) using the given angle relationships:
- Since \( \angle a \) and \( \angle b \) are corresponding angles and the lines are parallel:
\[
\angle a = \angle b
\]
Given:
\[
\angle a = 60^\circ
\]
\[
\angle b = 4x - 30^\circ
\]
thus
Figure in plane geometry formed by two rays or lines that share a common endpoint, called the vertex. The angle is measured in degrees using a protractor. The different types of angles are acute, obtuse, right, straight, and reflex.
