Answer:
80 in
Step-by-step explanation:
Because this is a right triangle we can find the length of the missing side using the Pythagorean Theorem
Given the hypotenuse and one leg we do
[tex]c^2-b^2=a^2[/tex]
where c = hypotenuse and b = leg
[tex]82^2=6724\\18^2=324\\6724-324=6400\\\sqrt{6400} =80[/tex]
so we can conclude that the missing side length is equal to 80
