In the given image, we are asked to find the values of \( t \) and \( u \) in the triangle geometry.

Let's break it down step by step:

1. **Identifying key elements**:
   - Triangle \( HIG \) is isosceles because two sides are marked as equal (between \( H \) and \( I \), and between \( G \) and \( F \)).
   - Angle \( \angle HIG = t \).
   - We are given \( \angle H = 36^\circ \) and \( HG = 2 \).

2. **Using properties of isosceles triangles**:
   - Since triangle \( HIG \) is isosceles, the base angles, which are angles \( \angle GIH \) and \( \angle GHI \), are equal.
   - Let these equal angles be \( \theta \).
   - Using the angle sum property of a triangle (\( \angle H + 2\theta = 180^\circ \)) in \( \triangle HIG \), we can find \( \theta \) and ultimately \( t \).

3. **Finding angle \( t \)**:
   - Since \( \triangle HIG \) is isosceles, we can apply the formula:
   \[
   \text{Sum of angles in a triangle} = 180^\circ
   \]
   \[
   t + 36^\circ + 36^\circ = 180^\circ
   \]
   Solving for \( t \):
   \[
   t = 180^\circ - 72^\circ = 108^\circ
   \]

4. **Finding \( u \)**:
   - Next, we need to find angle \( u \). Since \( \triangle GIF \) is also isosceles (as indicated by the two marked sides), we apply the same method for finding the base angles.
   - Assuming \( \triangle GIF \) is isosceles, the remaining angles can be calculated based on angle properties and side lengths, but without side lengths, we assume base angles are equal, simplifying the case.

Thus:
- \( t = 108^\circ \)
- \( u \) will depend on further provided geometric context (side lengths, specific triangle properties).

**Tip**: Always remember the sum of the angles in any triangle is always \(180^\circ\), a fundamental principle in triangle geometry.
