Step-by-step explanation:
For each problem you need to make sure that the angles are the same.
So x + 22 = 90
x = 90 -22 = 68 degree
For the second problem
7x + 10 = 8x
10 = 8x -7x
x = 10 degree
Answer:

Answer:
A collection of short stories.
Step-by-step explanation:
A classic novel is almost always fiction, which is not suitable for referencing. A commercial website publicly advertises its products or services. Again, not professionally referenceable. This leaves us with a collection of short stories. This option is correct because the stories come from realistic and personal accounts.
The list of scores from the given box-and-whisker plot are:
Lowest score: 20
Lower quartile (Q1): 30
Median: 60
Upper quartile (Q3): 80
Highest score: 100
The range = 80
<h3>How to Determine the Scores or Data Point from a Box-and-whisker Plot?</h3>
There are specifically 5 values that are referred to as the five-number summary which are displayed by a typical box-and-whisker plot. As shown in the image attached below, these values include the following:
- The minimum value which is the least value
- The lower quartile value (Q1)
- The median value
- The upper quartile value (Q3),
- The maximum value which is the largest data score.
Thus, from the box-and-whisker plot that is given in this question, the five-number summary are:
Minimum value (lowest score): 20
Lower quartile value (Q1): 30
Median: 60
Upper quartile value (Q3): 80
Maximum value (highest score): 100
The range = max - min = 100 - 20
The range = 80
