What is the value of tan e in the unit circle below?

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.

the answer

b. they are parallel and will never intersect.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
