Answer:
A. 12.4
Step-by-step explanation:
To find a, we'll use the Law of Sines that says:
![\frac{a}{sin(A)} = \frac{c}{sin(C)}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7Bsin%28A%29%7D%20%3D%20%5Cfrac%7Bc%7D%7Bsin%28C%29%7D)
And we'll isolate a to get:
![a = \frac{sin(A) * c}{sin(C)}](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7Bsin%28A%29%20%2A%20c%7D%7Bsin%28C%29%7D)
We first need to find A, which is easy. The sum of the interior angles of a triangle is 180 degrees... and we already have 2 of them, so:
A = 180 - 90 - 16.75 = 73.25
(converted 16°45' to 16.75)
Then we will plug-in the information we already have
![c = \frac{sin(73.25) * 13}{sin(90)} = 12.45](https://tex.z-dn.net/?f=c%20%3D%20%5Cfrac%7Bsin%2873.25%29%20%2A%2013%7D%7Bsin%2890%29%7D%20%3D%2012.45)
So, let's round it to 12.4 to match the answer A.
Answer: 0.35714285714 or 0.3751428571
Step-by-step explanation:
is that a fraction or a division symbol
Answer:
False
Step-by-step explanation:
Given that a high school reports that its students' SAT scores were down by 12% in one year. The next year, however, the test scores rose by 20%.
Let score initially be 100
Down by 12
Next year score 88
For succeedingyear
increase is 20% =![20% of 88=17.6\\](https://tex.z-dn.net/?f=20%25%20of%2088%3D17.6%5C%5C)
Score in the 2nd year = ![88+17.6 = 105.6](https://tex.z-dn.net/?f=88%2B17.6%20%3D%20105.6)
Hence overall scores improvement is 5.6% and not 8%
Answer:
2nd one
Step-by-step explanation:
sorry if that is incorrect it should be right though
