Which equation correctly shows the multiplication of the means and extremes in the proportion 13/78 = '/54?
OA) 13 - 54 = 78 - 9
B) 13 - 9 = 78 - 54
OC) 78 - 13 = 54.9
D) 13 - 9 = 78 - 13

means if you're already damaged some way when you take out a medical insurance you will not get full compensation for that injury that you already have.

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.
