Altitude above sea level is given in
positive values and below sea level is
given in negative values. If Ava
started at 120 feet above sea level
and thendecreased her altitude by
214 feet, what is her altitude now? *

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.

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

$450 i think. hope this ☺
