If m ∠ 2=63°, then m ∠ 3 is:
63°.
27°.
117°.
none of the choices are correct.

63 By definition.  Actually 1,2 and 3 are equal to each other since a is parallel to b.

∠2=∠3 because they are oposite angles (or something like that)

so
if ∠2=63°  and ∠2=∠3 then
∠3=∠2=63°

∠3=63°

answer is first option

108

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
