Answer:
x=10
A = 84
Step-by-step explanation:
A and B are supplementary angles so they add to 180 degrees
A + B =180
2x+76 + 5x+34 = 180
Combine like terms
7x+ 110 = 180
7x+110-110 = 180-110
7x = 70
Divide by 7
x = 10
Now find A
A = 5x+34
A = 5*10 +34
= 50+34
A = 84

Answer:
120poles
Step-by-step explanation:
Given
Length of each poles of the paddock = 30
Since a square has 4 sides, the perimeter of the square shaped paddock is what we are to look for.
Perimeter of a square = 4L
L is the length of each side of the paddock
Perimeter = 4(30)
Perimeter of the square = 120
Hence he used 120poles for the paddock
