Which of the following is an undefined term?
a. angle
b. line
c. ray
d. vertex

b. line

Step-by-step explanation:

We know that in geometry, there are three undefined terms and they are

1) point (no dimension)

2) line (one dimension)

3) plane (two dimension)

Therefore, from the given options the undefined term is 'line'.

In geometry a line is defined as a shape that is extending infinitely in two directions but has no width. It is one dimensional .

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
