Answer:

52 degrees

Step-by-step explanation:

If <DAE= 16, then <EAB=16, and <DAB=32

Since <DEA is a right angle, it equals 90

traingles =180, so <EDA = 180-16-90=74

This means angles EDC and ABC = 74+64 = 138

Since the interior angles of a quadrilateral =360,

<BCD=360-138-138-32 = 52

Answer:

BCD= 52

Step-by-step explanation:

since BCD is 64 take 64 from 180. 180 - 64 is 116 and since this is an equilateral triangle EBC also equals 64 so take 64 from 116. 116-64 is 52 which is your answer
