Let U = {b, f, k, m, p, r, u, y} A = {b, u, y) Find A. - Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. A'= 4 { } (Use a comma to separate answers as needed.)

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.
