Answer:
46
Step-by-step explanation:
If you take the fraction and divide it 2/11, it'll give you the decimal form of what you need, which will give you .18
Now your equation has become 254*.18, which you multiply instead of divide because you switched the form it is given in, and if you try to divide it will give you some obscure number.
Your answer from 254*.18 is 45.72, which you cant give .72 of a book, therefore you round up, making it so he has donated 46 books.
The answer is 25 degrees.
This is how you solve the equation, first you must know that the straight like ABC=180, DBC is 130, so the remaining amount is 50 degrees, BE is a bisector of ABD which means it splits ABD right down the middle. So ABE+EBD=50 degrees, 25+25=50 since both sides MUST be equal in order for BE to be a bisector of ABD.
