x = 6
Explanation:
use the pythagorean theorem which is <u>a^2 + b^2 = c^2</u>. 8 goes in either the a or b position and 10 is the longest side so it will go in the c position.
Find distance of side = (y₂- y₁) / (x₂- x₁)
you can get length and width
then area = length * width
perimeter = 2 * (length + width)
