Accepted Solution
A:
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
