Well this is an equilateral triangle so then a=b. so then b=4 as well. so then now you have a^2 + b^2=c^2.
4^2+4^2=c^2
16+16=c^2
32=c^2
Find the square root of 32 which is approximately 5.65685.
Find the square root of c^2 which is c.
so then 5.65685=c
Step-by-step explanation:
The midsegment is half of the side side AC.

Answer:
x = -95, y = 22.75, z = -6.625
Step-by-step explanation:
We start with the line that only has 1 variable, since that's easiest to solve.
2y + 162 = -28
2y = -190
y = -95
Then we go to the line that has 2 variables and substitute y with -95, since that's what y is equal to.
4x -95 = -4
4x = 91
x = 22.75
Then we do the last line with the answers we've gotten so far.
-14(22.75) - 3(-95) + 4z = 7
-318.5 + 285 +4z = 7
4z = -26.5
z = -6.625
