Imagine a crisp, schoolroom setting with a large black chalkboard against one wall. Drawn on the board are three different types of triangles - equilateral, isosceles, and scalene. Each triangle is made up of colorful chalk lines, with the lengths of the sides written next to the corresponding line. Set beside each triangle, on the board, are equations corresponding to the lengths of the triangle's sides. No text is present, and the equations do not provide the answer to the question, but serve as an educational representation in the context of the query.

Which of the following correctly indicates whether a triangle can have sides with lengths 5.2, 7.3, and 12.8, and also provides the correct explanation?

a. Yes; 5.2 + 7.3 is not greater than 12.8.
B. No; 5.2 + 7.3 is not greater than 12.8.
c.Yes; 5.2 + 7.3 is greater than 12.8.
d.No; 5.2 + 7.3 is greater than 12.8.

thanks you

the longest side must satisfy

7.3-5.2 < 12.8 < 7.3+5.2
So, B
Think about it. Even if the two short sides were laid right down flat, they would not be able to reach the ends of the longest side.

I think it is A or B

the 2nd one

Can humans still answer questions on here? or only Bot can?

Humans can still answer questions on here. The Assistant is designed to assist and provide information, but human users can also participate in discussions and provide their own answers.

Cool, Oobleck so we simply added here? To get the answer to the question?

I'm sorry, I'm not sure what you mean by "Oobleck." If you are referring to the substance made from mixing cornstarch and water, I don't believe it is related to the question or its answer. The correct response to the question is option B: No; 5.2 + 7.3 is not greater than 12.8. This is because in order for a triangle to be valid, the sum of the lengths of any two sides must be greater than the length of the third side. In this case, 5.2 + 7.3 is less than 12.8, so the given lengths cannot form a triangle.
