Answer:
The wire is approximately 42feet long
Step-by-step explanation:
We can mentally sketch out the shape that is formed between the guy wire and the antenna tower. This is simply a right-angled triangle with the opposite side being the height of the antenna (30 feet). The adjacent side is the distance on the ground between the point where the wire was fastened and the base of the antenna.
The hypotenuse side is the length of the wire we are looking for.
Parameters are given as:
Opposite : 30ft
Adjacent: 30ft
Hypotenuse: x feet
The hypotenuse = ![\sqrt{opp^2 + adj^2}](https://tex.z-dn.net/?f=%5Csqrt%7Bopp%5E2%20%2B%20adj%5E2%7D)
Hypotenuse =![\sqrt{30^2+ 30^2} \approx 42ft](https://tex.z-dn.net/?f=%5Csqrt%7B30%5E2%2B%2030%5E2%7D%20%5Capprox%2042ft)
Answer:
y = 16
Step-by-step explanation:
y = 11 - x
of x is -5, subtitute it into the equation
y = 11 - (-5)
y = 11 + 5
y = 16
For the first question, simply find a point that is on the line segment. For the second question, knowing that in quadrant iii the x values are negative and the y values are also positive using this fact find the point that has x negative and y positive.
