You draw a diagram of the fence post and then you use the measurements to find the length of the chain using the pythagorean theorem. The answer is
or 14.8
1. For y, I think that refers to the first picture attached. As you can see, each side of the triangle have the same short line drawn across it. It means that they are equal in length. That means the triangle is equilateral, which means each interior angle is 60°. Thus,
60 = 5y + 10
5y = 60 - 10
5y = 50
y = 50/5 =<em> 10</em>
2. As you can see in the second picture attached, Angles B and C are equal. That also means that their respective opposite sides are equal. So,
8x - 4 = 5x + 11
8x - 5x = 11 + 4
3x = 15
x = 15/3 = 5
Consequently,
BC = 4x - 2
BC = 4(5) - 2 = <em>18</em>
Answer:
Third answer choice
Step-by-step explanation:
Y intercept of the graph is -3 so you can eliminate the first two choices.
Then you see the slop is going up so its positive so you can eliminate the negative slope answer choice.
You are then left with the third answer choice and that is your answer.
(can I get brainliest please)
Answer: 
Step-by-step explanation:
Just plug these points into the slope formula 
A: (3,-1) = 
B: (-1/3, 2) = 
Now solve.
Simplify the numerator by changing the negative and minus to positive: 
This simplifies now to 3.
The denominator needs to be simplified by finding a common denominator.
The 3/1 needs to be multiplied by 3 on the top and bottom to get. 
Now with a common denominator we can subtract: 
Now we can put our simplified denominator and numerator back together.
Now KCF, keep change flip.
Now multiply across.
This is the final answer as it cannot be simplified any further.
