The mode is the number that appears the most out of a given sequence. 30 appears the most. Our mode is 30. The median is the middle number of a list of numbers from least to greatest. I will organize it for you. 20, 25, 30, 30, 30, 35, 45, 50, 100. To determine the median the fast way, cross out the smallest number with the largest number until you can no longer do so. 20,25,30,30,30,35,45,50,100 25,30,30,30,35,45,50 30,30,30,35,45 30,30,35 30. Our median is 30. We do not need to figure out the mean, since we have found our answer; Our mode and our median are equivalent. I hope this helps!
So we know it is <u><em>less than a right angle</em></u> and it is not a obtuse angle it is less than 90 degrees. 45 is less, 90 is equal(<em>not what we are looking for</em>) , 120, is greater, and 180 is greater which leaves us to our answer 45.
