Answer:
y=x-3
Step-by-step explanation:
To find slope, use m=y2-y1/x2-x1, using values of x and y from two different points. Once you have found slope, take another point and use the point-slope equation y-y1=m(x-x1) and substitute in slope for m and the point for x1 and y1. Isolate y by subtracting y1 from both sides.
Basically the answer is going to be 20
Answer:
d. 32.9
Step-by-step explanation:
To find c, 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:
![c = \frac{sin(C) * a}{sin(A)}](https://tex.z-dn.net/?f=c%20%3D%20%5Cfrac%7Bsin%28C%29%20%2A%20a%7D%7Bsin%28A%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 - 47.3 = 42.7
(converted 47°18' to 47.3)
Then we will plug-in the information we already have
![c = \frac{sin(90) * 22.3}{sin(42.7)} = 32.88](https://tex.z-dn.net/?f=c%20%3D%20%5Cfrac%7Bsin%2890%29%20%2A%2022.3%7D%7Bsin%2842.7%29%7D%20%3D%2032.88)
So, let's round it to 32.9 to match the answer number D.
