You review a lease for a new apartment. the lease requires you pay the first month's rent, last month's rent and a security deposit of one month's rent, at the time of signing. the monthly rent is $500. how much will you need at the time of signing?
the answer options are
a)$500
b)$1,000
c)$1,250
d)$1,500

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.
