Triangle ABC is defined by the points A (8, -2),

Mathematics
1 answer:
s344n2d4d5 [400]2 years ago
6 0

Answer:

First let's work out the lengths of each side using the equation

(y2-y1)²+(x2-x1)² and then find the square root of your answer

We get BC as root of 26

AB as root of 113

AC as root of 85

To get the perimeter of the triangle add up the values

root of 85+root of 113+root of 26=24.95 (use the unit specified)

I know the answer is a bit rushed but if you do have any questions let me know
