Answer:
Equilateral
Step-by-step explanation:
Since all sides are the same, the triangle is equilateral.
A:
Area: 289 m
Perimeter: 51 m
B:
Area: 4 m
Perimeter: 8 m
Answer:
r=sqrt45
Step-by-step explanation:
Answer:y = -5x + 11
Step-by-step explanation:
First, find the slope (m) of the line that passes through these points:
m = (1-6) / (2-1) = -5/1 = -5
Then use the point slope formula to find the equation of the line:
m = (y-y0)/(x-x0)
-5 = (y-1)/(x-2)
-5(x-2) = y-1
y - 1 = -5x+10
y = -5x + 11
X=25
4x-10=90
Add 10 to both sides
4x=100
Divide both sides by 4
