<h2>Here we go ~ </h2>
According to given figure,
[ By linear pair ]
now, we can see that :
[ By Exterior angle property of Triangle ]
Isolate the variable by dividing each side by factors that don't contain the variable.
x = 1
-6+3x+4=2-4x+3
-8+7x+1=0
7x=7
x=1
10 sides 180(10-2) 1800-360=1440/10 = 144
Answer:
y = -5x - 23
Step-by-step explanation:
Point-slope form:
y - 7 = -5(x + 6)
rearrange:
y - 7 = -5x - 30
y = -5x - 23
