discount price:

please explain how to do...

discount amount: .30 or

discount price: 0.90

Step-by-step explanation:

you will pay 0.9 for an item with the original price of 1.20 when discounted 25% off. you will pay 1.20-0.3=0.9

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.
