Answer:
x = 3.6
Step-by-step explanation:
Since the line segment from the vertex to the base is an angle bisector.
Then it divides the the opposite side into segments that are proportional to the other 2 sides, that is
[tex]\frac{6}{4}[/tex] = [tex]\frac{x}{2.4}[/tex] ( cross- multiply )
4x = 14.4 ( divide both sides by 4 )
x = 3.6
