HELP NEEDED Help me figure this out

252

Explanation:

First we need to find y.
Because there are three marks indicating that the measure of the angles are congruent, we know that all sides of the triangle are equal, so we can use that to find y.

5y-6=4y+12
y=18

Now substitute y into all the side equations:
5y-6 = 5(18)-6 = 84
4y+12 = 4(18)+12 = 84
6y-24 = 6(18)-24 = 84

Now that we know all the sides, just add these values together to get your perimeter:
84+84+84= 252

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.
