Answer: 57°
Given : In triangle PQR, the side PQ is 17, QR is 15, and PR is 14.
We use law of cosine formula
225 = 196 + 289 - 476 cos(P)
225 = 485 - 476 cos (P)
Subtract 485 on both sides
-260 = -476 cos(P)
= cos(P)
P = 
P= 56.89202
So measure of angle P is 57 degrees
The conclusion that can be made given the slopes of the quadrilateral is that: since the slopes of the opposite sides are equal, the opposite sides are parallel, therefore the quadrilateral is a parallelogram. (Option A is correct).
<em><u>Recall:</u></em>
- The slopes of the opposite sides of a parallelogram are always parallel.
- When two lines have a slope that is equal, the lines are said to be parallel to each other.
The slopes given shows are:
-1/2, 3/2, -1/2, and 3/2
This implies that the quadrilateral has two pairs of equal sides that are parallel to each other.
- Therefore, the conclusion that can be made given the slopes of the quadrilateral is that: since the slopes of the opposite sides are equal, the opposite sides are parallel, therefore the quadrilateral is a parallelogram. (Option A is correct).

I would solve this by calculating the percentage of dislikes that makes up to this amount of likes:
First one, "The True Science of Parallel Universes" would be:
5/300)*100 = 1.66
Second one, "did the Past Really Happen?" would be:
7/400)*100 = 1.75
The first one has less dislikes compared to likes. So "The True Science of Parallel Universes" is the video that is better liked
