In alessandro’s class, 5 students live in oakdale. there are 20 students in alessandro’s class. what percent of the students live in oakdale?

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: what statements

step-by-step explanation if you write the statements down then i could you.
