Answer:
no
Step-by-step explanation:
Imagine having sticks of these lengths. Attach the 4 and 5 to both ends of the 10. No way you can have them touch each other, not even when the triangle is flat.
The 4 and 5 add up to 9, that is less than 10.
The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.
