Question

Find EF in parallelogram CDEF.

Answer 1

Answer:

Step-by-step explanation:

EF = CD

FC = DE               These equal lines are properties of a parallelogram.

2y = 3y - 17          Add 17 to both sides

2y + 17 = 3y         Subtract 2y from both sides.

2y-2y+17 =3y-2y

y = 17

CD = y + 43

CD = 17+43

CD = 60

Since CD = 60 then FE = 60
