Answer:

B and C describe vertical angles

Step-by-step explanation:

Point R will be the common vertex of any possible pair of vertical angles.

For a given line segment, such as AE, one end will designate a side of one of the vertical angles, and the other end will designate a side of the other angle of the pair.

For example, Choice B uses the crossing segments TN and FL and identifies the vertical angles TRF and NRL.

Choice C uses segments FL and AE to identify the vertical angles LRE and FRA.

Choice A does not involve crossing segments. Choice D makes use of segment AE, but the other points S and N are not on the same segment.

If you had to subtract 426 from 913 how many times would you need to regroup ?

Kitty [74]

913

<u />487 would be your total but your question is how many times we would have to regroup, so.

<u />

First, you would have to borrow from the 1 because 3 is smaller then 6. Second, you would have to borrow from the 9 because you can't take 2 from 0. So there you would have to regroup twice to work this problem.

Hope that helps you. :-)
