Answer:
D
Step-by-step explanation:
Given that the segment is an angle bisector then the ratio of sides and base are equal, that is
= 
( cross- multiply )
10x = 72 ( divide both sides by 10 )
x = 7.2 → D
Commutative property of multiplication is shown above. This is because no matter how you put them, the answer will still be 140.
How does it want the answer to be? Like a fraction? If so, the answer would be 8/6 since rise over run. 8 up and 6 to the left.
