16 + 16 = 32
X * 4.75 = ?
32 + X = Y
You would add 16 plus 16 because there are TWO new books being bought, you multiply however many used books there are (X) by 4.5 then add that answer to 16+16, solve that, and you have your answer = Y
Hope this helps ^-^

Answer:
√3
Step-by-step explanation:
To recall trigonometric ratios, there is a special acronym known as sohcahtoa which stands for
- <u>s</u>in(x)=<u>o</u>pposite/ <u>h</u>ypotenuse
- <u>c</u>os(x)=<u>a</u>djacent/<u>h</u>ypotenuse
- <u>t</u>an(x)=<u>o</u>pposite /<u>h</u>ypotenuse
<u>Finding</u><u> the</u><u> </u><u>angle</u><u> </u>
We are given that,
To find the angle , take inverse of sin of both sides,
with the help of unit circle,we acquire:
<u>Finding </u>
simply plug in the value of theta:
using unit circle,we get:
and we're done!
