Answer:
x = 155
Step-by-step explanation:
155 and x are alternate exterior angles and alternate exterior angles are equal when a and b are parallel
x = 155
Answer:
the lowest point of the dry lake bed in the example has an elevation of -18 3/4 ft what number represents the change in elevation from the start of the path to the lowest point in the dry lake bed show your work (my teacher said she messed it up so it’s the same question just the numbers are -18 3/4 - (-12 1/2) explain how !
Answer:
CD ≈ 15.0
Step-by-step explanation:
calculate CD using the distance formula
d = ![\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }](https://tex.z-dn.net/?f=%5Csqrt%7B%28x_%7B2%7D-x_%7B1%7D%29%5E2%2B%28y_%7B2%7D-y_%7B1%7D%29%5E2%20%20%20%20%7D)
with (x₁, y₁ ) = C (7, - 4) and (x₂, y₂ ) = D (- 8, - 5)
CD = ![\sqrt{(-8-7)^2+(-5-(-4))^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-8-7%29%5E2%2B%28-5-%28-4%29%29%5E2%7D)
= ![\sqrt{-15)^2+(-5+4)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B-15%29%5E2%2B%28-5%2B4%29%5E2%7D)
= ![\sqrt{225+(-1)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B225%2B%28-1%29%5E2%7D)
= ![\sqrt{225+1}](https://tex.z-dn.net/?f=%5Csqrt%7B225%2B1%7D)
= ![\sqrt{226}](https://tex.z-dn.net/?f=%5Csqrt%7B226%7D)
≈ 15.0 ( to the nearest tenth )
<h2>(a)</h2><h2>{ 4 , 6 , 8 }</h2><h2>(b) </h2><h2>{ 2 , 4 , 5 , 6 , 7 , 8 }</h2><h2>(c)</h2><h2>{ 1 , 3 }</h2>
I would say the answer is "c"
