Which of the following accurately comapares 3√8 and √82?
a. √82is slightly more than 9,so√82 is less than 3 √8.
b. √82 is slightly less than 9, so √82 is less than 3 √8.
c. √82 is slightly more than 9, so √82 is greater than 3 √8.
d. √82 is slightly less than 9, so √82 is greater than 3 √8.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

answer is 144
