Given:
The measure of three sides of a triangle are 8, 7 and 14.
To find:
The measure of the angle opposite the side of length 8.
Solution:
According to the Law of Cosine:

Let a=8, b=7 and c=14, then by using Law of Cosine, we get



Taking cos inverse on both sides.



Therefore, the measure of the angle opposite the side of length 8 is 22.6 degrees.
The midpoint between these two would be -7, as you would add these two numbers, and then divide by two.
Answer:
8√13 units
Step-by-step explanation:
We use the distance formula.
The distance formula states that the distance between two points (x, y) and (a, b) is equal to:
d = 
Here, x = 6, y = -1, a = -18, and b = 15. Plug these in:
d = 
d =
= 8√13
The answer is thus 8√13 units.
