Question
Can you help me solve for the angles?
### Geometry Exercise

In the diagram provided, several lines intersect and form various angles. You are tasked with determining the measure of each labeled angle.

**Given:**
- A diagram of intersecting lines with the following known angles:
  - An angle labeled 60°
  - An angle labeled 112°
  - An angle labeled 40°
  - An angle labeled 70°

**Unknown Angles:**
- \( m = ? \)
- \( n = ? \)
- \( p = ? \)
- \( q = ? \)
- \( r = ? \)
- \( s = ? \)
- \( t = ? \)
- \( u = ? \)

**Diagram Explanation:**
- The diagram shows intersecting lines with right angles (indicated by small squares) at some intersections, which suggest angles of 90°.
- You need to use geometric properties, such as supplementary angles, complementary angles, or angle sum properties in triangles, to solve for the unknown angles.

### Task:

Find the measure of each unknown angle by applying your knowledge of geometry principles and provide a brief explanation for each calculation.
