In a trapezoid, two opposite sides are parallel and are called bases.
In this trapezoid, the top and bottom sides are parallel and are the bases.
The right side that intersects both bases is a transversal.
When parallel lines are cut by a transversal, same-side interior angles are supplementary. The measures of supplementary angles add to 180 deg.

x + 72 = 180

x = 180 - 72

x = 108 deg

The line plot shows the weight of the bags of beans.what is the average weight of the bags.
Setler79 [48]

Answer:

1/2

Step-by-step explanation:

So you have 12 bags total.

2 are 1/6 so their total weight is 1/3

2 are 1/3 so their total weight is 2/3

3 are 1/2 so their total weight is 3/2

4 are 2/3 so their total weight is 8/3

1 is 5/6 so their total weight is 5/6

Now add all of these up:

1/3 + 2/3 + 3/2 + 8/3 + 5/6 = 36/6 = 6

Then divide by the number of bags to get the average weight: 6/12 = 1/2
