The sum of all the angles in a trapezoid/trapezium is 360°.

90° + 60° + 150° + 3x = 360°

300° + 3x = 360°

3x = 360° - 300°

3x = 60°

x = 60°/3

x = 20°

Hope this helps!

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.
