Answer: C
Step-by-step explanation:
1+2e^x+1=9
2e^x+1=9-1
e^x+1= 8/2
e^x+1 = 4
Here we can applicate the Ln:
ln e^x+1 = ln 4
Applicating the log property for exponent:
(x+1).ln e = ln 4
Ln e = 1, so:
x+1 = ln 4
x = ln 4-1
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
