The answer is letter D, Angie is incorrect since triangles with two pairs of congruent sides and one pair of congruent angles do not necessarily meet the SAS orientation.
I’m pretty sure it’s -1
How you solve this is y2-y1/x2-x1
So 5-2/-3-1 which would be -1
Answer:
x = 6
Step-by-step explanation:
Given:

To find:
The length of QR.
Solution:
We have,

Then,
(CPCTC)



Divide both sides by 4.


Similarity,
(CPCTC)



Divide both sides by 2.

Now,


Therefore, the correct option is d.
