The definition of an angle bisector is a bisector that cuts an angle into two equal halves.

So BD bisects ∠ABC, therefore ∠ABD = ∠DBC

We can set the expressions inside them equal to each other, solve for x, and substitute it into the expressions again to find the total value of the angle.

4x - 15 = 3x + 12
- 3x         - 3x
______________
x - 15 = 12
   + 15   + 15
______________
x = 27

So x = 27, we can plug this back into an expression and do the same with the second one and add them, or, because we know they are equal, just multiply two once we find the value of the first one. 

4(27) - 15
= 108 - 15
= 93

Multiply 93 by 2.
93 x 2 = 186

Therefore m∠ABC is 186°

Hope this helps! :)

zaharov [31]

Answer:

$2.25/km

Step-by-step explanation:

The cost charged for a total taxi ride of 14\frac{2}{9}\ km was $32. To get the cost per km, we divide the cost charged for the total taxi ride by the total distance that was traveled by the taxi. The cost per km is given by:

Cost per km = \frac{Cost \ of\ money\ charged}{Total\ distance}=\frac{\$ 32}{14\frac{2}{9} \ km}=\frac{32}{\frac{128}{9} }=   \$2.25/km

Therefore the cost per kilometer is $2.25 per kilometer. Each kilometer traveled by the taxi cost $2.25.
