Have you considered plotting those four points and then connecting them? Here's a hint:
(5, -4) and (-1, -4) lie on the same horiz. line.
What can you say about (-1, 2) and (5, 2)?
Answer:
35/4
Step-by-step explanation:
-3 1/2=-7/2
-12 1/4=-49/4
------------------
-7/2-(-49/4)
-7/2+49/4
-14/4+49/4
35/4

Answer:
≈![7.07](https://tex.z-dn.net/?f=7.07)
Step-by-step explanation:
1. You know that the triangle described in the problem is a right triangle and the problem gives the length of the opposite side. Therefore, you can calculate the lenght of the hypotenuse as following:
![sin\alpha=opposite /hypotenuse](https://tex.z-dn.net/?f=sin%5Calpha%3Dopposite%20%2Fhypotenuse)
Where:
![\alpha=45\°\\opposite=5\\hypotenuse=r](https://tex.z-dn.net/?f=%5Calpha%3D45%5C%C2%B0%5C%5Copposite%3D5%5C%5Chypotenuse%3Dr)
2. When you substitute the values above and solve for the hypotenuse, you obtain:
![sin(45\°)=5/r\\r=5/sin(45\°)](https://tex.z-dn.net/?f=sin%2845%5C%C2%B0%29%3D5%2Fr%5C%5Cr%3D5%2Fsin%2845%5C%C2%B0%29)
≈7.07
