Transcribed Image Text:**Exercise 10: Find the Measure of Each Missing Angle**
A diagram of a geometric figure is shown, including two connected triangles. Here are the specifics:
- The larger triangle is annotated with the angle measures of 59° and 127°.
- There is an internal line dividing the triangle, creating a smaller triangle within the larger one.
- The vertices of the triangles are labeled with numbers 1, 2, 3, 4, and 5 corresponding to the angles.
**Tasks: Determine the measures of the following angles.**
- \( m\angle 1 = \) ______
- \( m\angle 2 = \) ______
- \( m\angle 3 = \) ______
- \( m\angle 4 = \) ______
- \( m\angle 5 = \) ______
**Instructions:** Use properties of triangles and adjacent angles to find the missing angle measures. Consider that the sum of angles in a triangle equals 180° and adjacent angles on a straight line sum to 180°.
**Mathematics Corner:** Reviewing key concepts related to angles in triangles and the ability to deduce unknown angles using known measurements.
