If m angle3 = 74°, find each measure. note: l || m

a.) m angle 1 =

b.) m angle 2 =

c.) m angle 4 =

d.) m angle 5 =

e.) m angle 6 =

f.) m angle 7 =

g.) m angle 8 =

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.
