Answer:
EF = 36
Step-by-step explanation:
FE and GD are congruent
2u - 36 = u
subtract 2u from both sides (-36 = -u)
divide each side by -1 ( u = 36)
now that you know the value of u plug it into the equation 2u -36
the equation is now 2(36)-36
2 times 36 equals 72
now do 72 - 36 and you get 36
that is the value of line segment EF
