Answer:
<h2>y = 31</h2>Step-by-step explanation:
We know: opposite angles in a parallelogram have the same measure.
Therefore we have the equation:
<em>subtract y from both sides</em>
We know: the sum of the angle measures in the triangle is 180°.
Therefore we have the equation:
<em>subtitute x = 87</em>
<em>subtract 149 from both sides</em>

Step-by-step explanation:
Given the data:
30 27 22 25 24 25 24 15 35 35 33 52 49 10 27 18 20 23 24 25 30 24 24 24 18 20 25 27 24 32 13 13 21 2 37 35 32 33 29 3 28 28 25 29 31
Number of classes = 5
Class width : Range / number of classes
Class width = (maximum - minimum) / 5
Class width = (52 - 2) / 5 = 50/5 = 10 + 1 = 11
