On saturday at the boxerville carnival, 800 people attended. on sunday, 650 people attended. on monday, 250 people attended. on tuesday, 350 people attended. how many people attended the boxerville carnival on the weekend?

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
