Angle S is 64.62
1. Draw your picture.
2. Find invert cosine of 6/14
133=x + (x+5) + (x+14)
133 = 3x+19
3x=114
x= 114/3 =38
5+38 =43
38+14 =52
check: 38 +43 +52 = 133
3 sides are : 38, 43 & 52
Answer:
Basically multiply the x and y coordinates of each point by 1/2
For example, I'll do C which is ( -2 , 10 )
-2 * 1/2 = -1 and 1/2 * 10 = 5
The new coordinate is ( -1 , 5 )
Now you can try the other points
The answer is C ... or you could say n<3
