Question

### Geometry Module: Circle and Angle Properties

#### Problem Description

**Points A, B, C, and D lie on circle O as shown. AC is a diameter of circle O.**

The image depicts a circle labeled `O`, with points `A`, `B`, `C`, and `D` positioned on the circumference of the circle. The line segment `AC` is the diameter of the circle.

There are three key angles marked in the circle:
1. ∠DAB, denoted as `x°`.
2. ∠DBA, labeled as `34°`.
3. ∠OBA, marked as `32°`.
4. ∠AOD, denoted as `y°`.

#### Questions
1. Calculate the value of angle `x`.
2. Calculate the value of angle `y`.

- Input fields:
- $ x = \_\_\_ $
- $ y = \_\_\_ $

#### Graph Description
In the diagram, circle `O` is shown with `AC` as its diameter. Points `A` and `C` are the endpoints of the diameter. Lines `AD`, `AB`, `DC`, and `DB` are drawn connecting the relevant points. The angles to calculate, `x` and `y`, are shown near points `A` and `O` respectively, with given angle measures for ∠DBA and ∠OBA.

Students are required to use knowledge of circle geometry and properties of angles in a circle to determine the values of `x` and `y`.

#### Key Concepts to Consider
- Angle subtended by a diameter in a circle is 90°.
- Sum of angles in a triangle is 180°.
- Properties of cyclic quadrilaterals (angles in a cyclic quadrilateral add up to 360°).

Use these properties to solve for the unknown angles `x` and `y`.

#### Answers
- $ x = \_\_\_$
- $ y = \_\_\_$

Fill in your answers after performing the necessary geometric calculations.
