Answer: 17.5 is located between them.
Step-by-step explanation:
To find out which number is located between the numbers, find their mean average which sum of the numbers divide by the number of values.
15 + 20 = 35
35 / 2 = 17.5
Let D be the endpoint of the angle bisector opposite A on lying on side BC. The angle bisector theorem states that the ratio of BD to CD is equal to the ratio of AB to AC. In this case, you have

(This is the same equation that you have, it's just rearranged.)
Multiply both sides by

and 15.


Now you can solve for

.


Answer:
x = 0
Step-by-step explanation:
2(x - 3) + 9 = 3(x + 1) + x
2x - 6 + 9 = 3x + 3 + x
2x + 3 = 4x + 3
2x - 4x = 3 - 3
-2x = 0
2x = 0
x = 0/2
x = 0
