Answer:
B
Step-by-step explanation:
cosA =
=
= ![\frac{12}{13}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B13%7D)
cosC =
= ![\frac{5}{13}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B13%7D)
sinC =
=
= ![\frac{12}{13}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B13%7D)
tanC =
=
= ![\frac{12}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B5%7D)
Then
cosA = sinC → B
Small, because 1 divided by 8 = 0.125, and 3 divided by 4 = .75 Hope this helps!
Answer: C
Step-by-step explanation:
You have two pairs of congruent angles - angles S and V, and the right angles.
The answer is 9.43 because you have to add both of them if your in college how do you not get this?
First find the number of mysteries by multiplying 85 books by 20%:
80 x 0.20 = 17
Now add mysteries and adventure books together and subtract from 85 to find the number of fantasy books:
17 + 18 = 35
85 - 35 = 50
So 50 out of 85 books are fantasy.
This is written as 50/85 which simplifies to 10/17.
