In the figure, j | k and mZ2 = 117°
What is the mZ3?

if angle 2 is 117 degrees, angle 3 is supplemental and would be 63 degrees.

180-117=63

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.
