Answer:
Multiplicative Identity Property
Step-by-step explanation:
M∠BDC=half the arc it faces=1/2 of 54=27
BD is the diameter, so m∠C=90
m∠DBC=180-90-27=63
Answer:
Step-by-step explanation:
21. (24)(2)/6+4=48
=48/6+4
=8+4
=12
4/7=N/12 cross multiply
7N=4*12
7N=48
N=48/7
So your answer is 6 6/7 or 6.8571428
