If the ratio of a circles sector to its total area is 5/16 what is the measure of its sectors arc?

it is c

Step-by-step explanation:

you dot need one i just did that same test and that was the answer

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.

because they could drop even lower..
