Answer:
see below
Step-by-step explanation:
The perimeter is the sum of all the sides
A + B+ C+ D + E = 190
x+5 + x+10 + -5(x-20) + 6x-10+ 2x+4(20-x) = 190
Distribute
x+5 + x+10 -5x+100 +6x-10 +2x +80 -4x = 190
Combine like terms
x + x -5x-4x+6x +2x +80+10+100 -10+5 = 190
x +185 = 190
Subtract 185 from each side
x+185-185 = 190-185
x = 5
Side A = x+5 =5+5 =10
Side B = x+10 = 5+10 =15
Side C = -5(x-20) = -5(5-20) = -5(-15) = 75
Side D = 6x-10 = 6(5) -10 =30-10 = 20
Side E = 2x+4(20-x) = 2*5 +4(20-5) = 10+4(15) = 70
Answer:
1,183
Step-by-step explanation:
i'm not sure but i added the inside up so i think this is correct
I believe the angle is 60°
i think it would be it, since you're dividing the amount into three friends.
The slope is -3 the y intercept is -1
