Answer:
Can not be 3.6cm
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. 5+1.4=6.4 . Therefore, the length of the third side must be less than 6.4 . Now, to make sure the third side isn’t too long, you can take the difference of the other two sides. 5–1.4=3.6 Therefore, the length of the third side must be greater than 3.6. Now we have an inequality. If x is the length of the third side, 3.6<x6.4. Since you’re asking what cannot be the length of the third side, that would be anything greater than or equal to 6.4 or less than or equal to 3.6.
