Write the ratio of corresponding sides for the similar triangles and reduce the ratio to lowest terms. a 4/10=5/8=2/5 b 4/8=5/10=1/2 c 10/4=8/5=5/2 d 4/5=8/10=4/5

As shown in the figure we have right triangles
So by dividing the small hypotenuse over the large hypotenuse
∴

∴ The correct choice is (b)
    b) 4/8=5/10=1/2

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.
