u is at (1,-2)
V is at (-6,-6)
using distance formula it is about 8.06 long
so Answer is C
<h2>
Answer: 55 degrees</h2>
Step-by-step explanation:
Every triangle has 3 sides and 3 interior angles whose measures sum to 180 degrees. For example, a triangle with angles
,
and
:
![\theta+\alpha+\beta=180\º](https://tex.z-dn.net/?f=%5Ctheta%2B%5Calpha%2B%5Cbeta%3D180%5C%C2%BA)
Following this rule, we will apply it to the angles XYZ, YXZ and the unknown XZY:
![XYZ+YXZ+XZY=180\º](https://tex.z-dn.net/?f=XYZ%2BYXZ%2BXZY%3D180%5C%C2%BA)
![50\º+75\º+XZY=180\º](https://tex.z-dn.net/?f=50%5C%C2%BA%2B75%5C%C2%BA%2BXZY%3D180%5C%C2%BA)
![XZY=180\º-50\º-75\º](https://tex.z-dn.net/?f=XZY%3D180%5C%C2%BA-50%5C%C2%BA-75%5C%C2%BA)
Finally:
![XZY=55\º](https://tex.z-dn.net/?f=XZY%3D55%5C%C2%BA)
I think it may be 1,680B but I'm not too sure...
