Answer:
A. 7.07 units
Step-by-step explanation:
Use the distance formula for coordinates:
![d=\sqrt{(x_{2}-x_{1})^2 +(y_{2}-y_{1})^2 }](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28x_%7B2%7D-x_%7B1%7D%29%5E2%20%2B%28y_%7B2%7D-y_%7B1%7D%29%5E2%20%20%20%7D)
Fill in the coordinates accordingly:
![d=\sqrt{(1-(-4))^2+(-3-2)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%281-%28-4%29%29%5E2%2B%28-3-2%29%5E2%7D)
which simplifies down to
![d=\sqrt{25+25}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B25%2B25%7D)
which is of course
![d=\sqrt{50}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B50%7D)
Plug that into your calculator and you'll get the answer
Answer:
1. false
2. true

5. true
6. false
Step-by-step explanation:

1. First of all, this is a isosceles triangle, meaning measurement I=58°, which makes it way easier to find T.
![58 + 58 + x = 180](https://tex.z-dn.net/?f=58%20%2B%2058%20%2B%20x%20%3D%20180)
![116 + x = 180](https://tex.z-dn.net/?f=116%20%2B%20x%20%3D%20180)
![x = 64](https://tex.z-dn.net/?f=x%20%3D%2064)
1. m{t}°=64 m{I}°=58
2. This one is easy because algebra is the key.
![100 - x + 30 + 4x + 7x = 180](https://tex.z-dn.net/?f=100%20-%20x%20%2B%2030%20%2B%204x%20%2B%207x%20%3D%20180)
Add like-terms.
![130 +10x = 180](https://tex.z-dn.net/?f=130%20%2B10x%20%3D%20180)
![10x = 50](https://tex.z-dn.net/?f=10x%20%3D%2050)
![\frac{50}{10} = x = 5](https://tex.z-dn.net/?f=%20%5Cfrac%7B50%7D%7B10%7D%20%20%3D%20x%20%3D%205)
x=5
The only thing that confuses me is the y. Is it 7xy, y as a side, or what? Feel free to reply
