Answer:

x = 66°

Step-by-step explanation:

Sum of the angles of a pentagon is 540°. So, set the expression equal to that and solve for x:

8x + 12 = 540

x = \frac{540-12}{8} = 66

Thus, x = 66°.

katie has red 32% of a book if she has to read 80 pages how many more pages does Katie have left to read
galben [10]
In this question, the information that Katie has already read 32% of a book that has a total of 80 pages is of great importance. This information is enough to find the required answer to the question.
Total number of pages Katie has to read = 80
Percentage of pages that Cathie read = 32%
Number of pages that Katie read = (32/100) * 80
                                                     = 256/10
                                                     = 25.6 pages
Then
The number of pages that Katie have left to read = 80 - 25.6
                                                                               = 54.4 pages
So Katie has 54.4 pages left to read.
