Answer:angle ECF = 32 degrees

Explanation:

BFED is a parallelogram. In a parallelogram, the opposite sides are equal. It means that BF = DE

and EF = DB

Therefore, DB = 6

Also, AD = DB = 6

To find AE, we will apply trigonometric ratio. It is expressed as

Sin# = opposite side / hypotenuse

Opposite side = 6

# = 32

Hypotenuse = AE

Sin32 = 6/AE

AE = 6/Sin 32 = 6/0.5299 = 11.32.

EC = AE = 11.32

To find angle ECF, we would apply trigonometric ratio. It is expressed as

Sin angle ECF = 6/11.32 = 0.53

angle ECF = arcsin0.53 = 32
