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
