Not necessarily. Triangle ABC could be isosceles. Since the problem gives no further information about the third side, you cannot conclude definitely that ABC is equilateral.
Answer:
<h2>Line B</h2>
Step-by-step explanation:
When naming lines, you can use the label of the line, in this case, m, and can also name the points in either direction, since the line goes on forever in both directions (it's different with rays). The leaves only line B as an answer.

Lets solve for the finance charge in dollars when Tim agreed to pay $36 for 12 months. We formulate an equation by enumerating the following:
1.) Total amount that Tim paid for the DVD player is $36 times 12 months is equal to $432.
2.) Total amount paid is the summation of DVD player original price plus the result of multiplication of finance percent charge and original price.
Equation is $365+($365x%charge)=$432.
Solve for % charge,
%charge = ($432-$365)/$365
%charge =0.1834 or 18.4%
Therefore, the finance charge in dollar is $67.
