Help with my math homework, this is pretty easy to do ! But I need to turn it in a sap and It’s going to take me a long time to actually, figure it out

18 is less than 34

16 ≤ 2x

x minus 13 multiplied by 5 is greater than or equal to 24

7> -15

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.
