How do I classify an angle by its angle measures

If a triangle looks like and Big L and has the measurement of 80 degrees then that would be considered a right angle. If its less than that and kind of looks like this < or this > or is less than 80 then that would be an acute. If its bigger than both of those  and is bigger than 80 then the other option would leave you with Obtuse. <3

Step-by-step explanation:

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
