x =112
Step-by-step explanation:
The sum of the angles of a triangle add to 180
Two angles are 34 and 34. Let the third angle be x
34+34+x = 180

68+x = 180
Subtract 68 from each side
68-68 +x = 180-68
x =112

Answer: The number of books she should put on each shelf = 7
Step-by-step explanation:
Given: Total books = 116
Total shelves = 16
To determine : The number of books she should put on each shelf, we first divides the total number of books by the total shelf.

Hence, The number of books she should put on each shelf = 7.
