Gina wants to ride the waves at flagship pier in galveston so she she rents a surfboard for $5 and hour plus an initial or beginning payment of $20 for how many hours can gina rent a surfboard if she has $90

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.
