**Diagram Analysis and Problem #8**

This image presents a diagram with several intersecting lines, forming various angles labeled from *a* to *i*. Some angles have known measurements, specified in degrees, and are crucial for solving the relationships between these angles.

**Known Angles:**
- Angle at the top is 60°.
- Angle adjacent to the line segment marked as *d* is 65°.
- Angle adjacent to the line segment marked as *g* is 55°.

**Diagram Description:**
- The diagram features two intersecting lines creating an upper angle of 60°.
- There are three main lines intersecting from left to right at different angles.
- Labeling of the angles begins from the top and moves downward or laterally.

**Objective:**
Determine the values of the unknown angles: *a, b, c, d, e, f, g, h,* and *i*. Fill in the blanks below with the appropriate angle measurements.

**Blanks to Fill:**

- a = ___________
- b = ___________
- c = ___________
- d = ___________
- e = ___________
- f = ___________
- g = ___________
- h = ___________
- i = ___________

Use angle relationships such as supplementary angles, vertically opposite angles, and alternate interior angles, to resolve the values of the unknown angles.

### Problem #7

#### Diagram Explanation

This diagram illustrates two intersecting lines forming four angles labeled as \(a\), \(b\), \(c\), and \(d\). The diagram indicates the measures of two angles adjacent to \(a\):

- The angle across from \(a\) is labeled 51°, making these vertical angles.
- The angle adjacent to \(a\) on the right side is labeled 52°, forming a linear pair with \(a\).

#### Questions and Answers

For the values of the angles, fill in the blanks:

- \(a =\) __________
- \(b =\) __________
- \(c =\) __________
- \(d =\) __________

#### Answer Explanation

To solve for the unknown angles:

- Vertical angles are equal, so \(a = 51°\).
- Linear pairs sum to 180°, so \(a + 52° = 180°\). Therefore, \(c = 128°\).
- \(b\) is vertical to \(c\), so \(b = 128°\).
- Opposite of \(b\) forming a linear pair is \(d\), so \(d + 51° = 180°\). Therefore, \(d = 129°\).

Replace the blanks with these calculated angle measures to complete the assignment.
