Answer:
d. 32.9
Step-by-step explanation:
To find c, we'll use the Law of Sines that says:

And we'll isolate a to get:

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 - 47.3 = 42.7
(converted 47°18' to 47.3)
Then we will plug-in the information we already have

So, let's round it to 32.9 to match the answer number D.
The final answer for this question would be.....
8.8n^2+16n+0.1
Hope this helps!!!!
In mathematics, every integer is a rational number, hence a whole number 8 can be written as 8/1. 1/3 x 8 = 8/3 in fraction form. 1/3 x 8 = 2.6667 in decimal form.
