The perimeter of a triangle is:
P = a + b + c
We are given that:
b = a + 3
c = 2 a – 3
Therefore:
68 = a + a + 3 + 2 a – 3
68 = 4 a
a = 17
and,
b = a + 3 = 20
<span>c = 2a – 3 = 31</span>
Theoretical would be approximately 26.67
Experimental is 0.24 (24%)
First, find the slope of the line contains the points (1,-6) and (-2,6) using slope formula
m =

plug in the numbers
m =

m =

m =

m = -4
Second, determine the slope of perpendicular line
The slope of the perpendicular line is the opposite and reciprocal from the other line. Thus, the slope is
