Apply the Triangle Inequality Theorem and determine which option could be the third side of a triangle if the first two sides measure 4 and 6.(1 point)

9

1

11

2

Answer 1

Use the triangle inequality: |6 − 4| < x < 6 + 4, so 2 < x < 10.

Among the choices only 9 satisfies this, so 9 could be the third side.
