Answer:
The distance between points 8 and -5 is 13
Step-by-step explanation:
We need to find distance between points 8 and -5
The formula used to find the distance is: ![Distance=|b-a|](https://tex.z-dn.net/?f=Distance%3D%7Cb-a%7C)
Absolute value is used to get only positive values. i.e |-1|=1 if required.
We are given: b=8 and a=-5
Putting values and finding distance
![Distance=|b-a|\\Distance=|8-(-5)|\\Distance=|8+5|\\Dstance=|13|\\Distance=13](https://tex.z-dn.net/?f=Distance%3D%7Cb-a%7C%5C%5CDistance%3D%7C8-%28-5%29%7C%5C%5CDistance%3D%7C8%2B5%7C%5C%5CDstance%3D%7C13%7C%5C%5CDistance%3D13)
So, the distance between points 8 and -5 is 13
You would have to find the height.
To do this, you cut the triangle from the upper vertex to the base to create two new triangles.
Then you use the Law of Cosines. You could use the google calculator for this by searching “law of cosines calculator” and inputting the values, but in case of a test, the formula is a^2 = b^2 + c^2 - 2bc cosA
If you could provide an example of a triangle, I will gladly help you with the steps! Hope this helped!
7+8= 15 and 14-8= 6 hope that help
Hmmm recall, p=3, and "p" is the distance from the vertex to either, the focus or directrix, so if the focus is 3 units to one-side of the vertex, the directrix is 3 units to the other side
