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

Answer:
Perimeter of rectangle = 36 meters
Step-by-step explanation:
We have given,
Length of rectangle = 14 meters
Width of rectangle = 4 meters
Perimeter of rectangle given as:
Perimeter = 2 (Length + width)
To get perimeter plug values of length and width into perimeter formula.
i.e Perimeter = 2 ( 14 + 4)
Perimeter = 2 * 18
Perimeter = 36 meters
Hence the perimeter of rectangle is 36 meters
U would replace ur -4 with the x’s so ur problem would look like <-2(-4)-10> and then solve that and u would get (2) for ur answer...
