2. Which of these describes a unique polygon?A. A triangle with angles 30°, 50', and 100°B. A quadrilateral with each side length 5 cmC. A triangle with side lengths 6 cm, 7 cm, and 8 cmD. A triangle with side lengths 4 cm and 5 cm and a 50° angle

Accepted Solution

Answer:D Step-by-step explanation:we know it is not b because it would make a square. it is not a because if you add all the angles it adds up to 180 so that is fine we know it is not c because the largest side 8 is less than the two shortest sides that add up to be 13 so we are left with D hope that helps
