Option D:
SAS
Solution:
Given 
To prove that 
In ΔPQR and ΔRSP,
(given side)
(given)
By alternative interior angle theorem,
∠PRS ≅ ∠QPR (angle)
By reflexive property of congruence,
(side)
Hence by Side-Angle-Side (SAS) congruence rule,
ΔPQR ≅ ΔRSP
Option D is the correct answer.
Hence the missing reason is SAS.

Answer:
Blank 1: x
Blank 2: 1.5
Step-by-step explanation:
So the equation you'll use is (18,000 × .041)y+18000. Y is your years which is 20. So all you need to do is plug it in to get (18,000 × .041)20+18000 and when solved is 32,760 downloads by 2030
So let's start by guesstimating the slopes:
the green line has a slope close to -x, but more negative than that, possibly -2; the pink line has a slope close to +x, but higher towards +2.
Next let's look at the solution: the two lines intersect at the point (1, -1).
**you could just simple plug that x (1) into all the equations, but let's rule out answers anyway. ;)
A) is incorrect because the slopes of -1 and +1 are off from out predicted -2 and +2
B) is incorrect because of a similar reason, the slopes of +3 and +1 don't make any sense
C) Ooh, we do have a +2 and -2 for the slopes, and... violà! plug in 1 for the x's and we get -1 for the y in both equations
D) slopes are closer than in A and B, but plugging in 1 doesn't get us -1
So the correct answer is:
C) y = 2x - 3 and y = −2x + 1
