Answer:
Area of triangle is 9.88 units^2
Step-by-step explanation:
We need to find the area of triangle
Given E(5,1), F(0,4), D(0,8)
We will use formula:

We need to find the lengths of side DE, EF and FD
Length of side DE = a = 
Length of side DE = a = 
Length of side EF = b = 
Length of side EF = b = 
Length of side FD = c = 
Length of side FD = c = 
so, a= 8.60, b= 5.8 and c = 4
s = a+b+c/2
s= 8.6+5.8+4/2
s= 9.2
Area of triangle=
So, area of triangle is 9.88 units^2
50 degrees because 50+50= 100 +80 = 180 and there is 180 degrees in a triangle

Well, you would simply need to use the distributive property!
-(2)x-(2)2+(2)y-(2)9=1
-2x-4+2y-18=1
Then you need to add/subtract so the similar numbers are together.
-2x+2y-22=1
-2x+2y=23
x+2y=-11.5
x+y=-5.75
