Given 17 books.
Total 56 b<span>ooks.
How many books were in her collection before her teachers donation?
</span>
First lets write an equation:
b = books before
17 + b = 56
Lets solve for b:
17 + b = 56
Inverse Operation:
56 - 17 = b
56 - 17 = 39
b = 39
Check:-
17 + b = 56
17 + 39 = ?
17 + 39 = 56
Correct!
There were 39 books in her collection before her teacher donated her books.
The equation is: 17 + b = 56.
b = 39

Im not sure but since the angle you have is 52 and this is an isosceles triangle so you will do 180-52 over 2 to get the other 2 angles which will be 64 each and you want the exterior angle which is 180 aswell so you will do 180-64 which will be 116
