Answer:
- Two unique triangles possible
Step-by-step explanation:
Given two sides of 10 cm and one 40° angle
If we use these, we'll get isosceles triangle with:
1. Included 40° angle.
Then the other angles will be same and measure:
- (180° - 40°)/2 = 70°
2. Adjacent 40° angle. Then one of the angles must be 40° angle as opposite of 10 cm sides.
The remaining angle will measure:
- 180° - 2*40° = 100°
There no more unique triangles possible, so the answer is two.
