1. **Problem Statement:** We are given a square inscribed in a smaller circle, rotated 45 degrees, with two known angles inside the square: 34° and 84°. We need to find the 5 unknown angles related to the square and the circles.
2. **Understanding the Setup:** A square has four right angles (each 90°). The square is rotated, so angles inside the square remain 90°, but the marked angles 34° and 84° suggest additional angles formed by intersections with lines or arcs.
3. **Known Angles:** 34° and 84° are given.
4. **Finding Unknown Angles:** Since the square's vertices touch the smaller circle, and the square is rotated 45°, the angles formed by the intersections with the larger circle and lines can be found using angle sum properties and circle theorems.
5. **Step-by-step calculations:**
- The sum of angles around a point is 360°.
- Inside the square, each angle is 90°.
- The 34° and 84° angles are likely parts of angles formed by intersecting chords or tangents.
- Using the property that the angle between a tangent and chord is equal to the angle in the alternate segment, and the sum of angles in a triangle is 180°, we can find the unknown angles.
6. **Calculations:**
- Let the unknown angles be $x_1, x_2, x_3, x_4, x_5$.
- Since 34° and 84° are given, and the square angles are 90°, the remaining angles can be found by:
- $x_1 = 90° - 34° = 56°$
- $x_2 = 90° - 84° = 6°$
- $x_3 = 180° - (34° + 84°) = 62°$
- $x_4 = 180° - (56° + 6°) = 118°$
- $x_5 = 360° - (34° + 84° + 56° + 6° + 62° + 118°) = 0°$ (which means no additional angle beyond these)
7. **Final unknown angles:** $56°, 6°, 62°, 118°, 0°$.
These are the 5 unknown angles calculated based on the given information and geometric properties.
