two sides of a traingle are of length 4 cm and 2.5 cm the length of third side of the traingle cannot
Answers
Step-by-step explanation:
To solve this, you need to use the Triangle Inequality Theorem. That states that the length of the greatest side of a triangle must be less than the sum of the other two sides. To make sure the third side isn’t too long, you can sum the other two sides. 4+1.5=5.5. Therefore, the length of the third side must be less than 5.5. Now, to make sure the third side isn’t too long, you can take the difference of the other two sides. 4–1.5=2.5. Therefore, the length of the third side must be greater than 2.5. Now we have an inequality. If x is the length of the third side, 2.5<x<5.5. Since you’re asking what cannot be the length of the third side, that would be anything greater than or equal to 5.5 or less than or equal to 2.5.
