You have to add all the common terms together.
Answer:
<h3>Sv is angle bisector of rst.</h3>
Answer: 2.5, 21/8, √25, pi, √19
You just add the thickness of the 2 books which is 237+3.56=240.56
Then you round the hundredth place which is 5 and next to it is the number 6 and that’s 5+ so it’s going up by a number. The answer is 240.6 inches tall. I tried explaining it well so sorry if you didn’t understand.
