Answer:
Step-by-step explanation:
The angles of a quadrilateral have to add up to equal 360. That means that
1x + 2x + 3x + 4x = 360 and
10x = 360 so
x = 36. Then
2x = 72 and
3x = 108 and
4x = 144
Angle A and angle D are opposite angles, as are angles B and C. This is because opposite angles are supplementary.
multiply everything by 8
2x+16 = -5x-40
-16 on both sides
2x = -5x-56
+5x on both sides
7x = -56
x=-8
so the first option
The lower value is 15,The upper value is 100, The median is 32 and 39, The lower quartile is 30, the upper quartile is 50, and the interquartile range is 36.
