Answer:
See below
Step-by-step explanation:
1 . Missing angle
Sum of interior angles in the triangle = 180°
- 180° - (105° + 29°) = 36°
2. Angle 1
- Angle 1 is exterior angle of the triangle
- Angle 1 = 55° + 78° = 133°
3. Angle 2
- Angle 2 = 180° - (55° = 78°) = 47°
4. The sum of exterior angle and adjacent interior angle equals 180°
If they are equal, then each will measure 180°/2 = 90°
So it is possible with the right triangle
