Cody is combining all of the juice shown to make

a fruit cocktail. Does the expression

(51 + 24 + 77) - 4 show how to calculate the

number of

cup servings? Explain.

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.

its line 2 i just added the rest or else it wouldn't let me answer
