Answer:
x=26
Step-by-step explanation:
exterior angles theorem meaning they're equal to each other.
5x+7=8x-71
add 71 to 7
5x+78=8x
subtract 5x from 8x
78=3x
divide 78 and 3
x=26
to check your work plug 26 into each equation:
5(26)+7= 137°
8(26)-71= 137°
because they're the same you know that x must equal 26

A = s2 (Area of a square is its side squared)
P = 4s (perimeter of a square is a side times 4)
A = 324 (the area of this square is 324 ft2)
fencing = $7 per foot
Let's find the side through the area. Find the root:
√324 = √s2
18 = s
Now the perimeter:
P = 4 * 18 = 72
Now to find how much the fencing will cost:
72 * 7 = 504
The answer is C because it is you have to multiply -3/4 by something negative to get positive 1, and C is not only the only negative number, it is the only one that works. Hope this helps!
