Answer:
A
Step-by-step explanation:
O because that is the number that you always start off.
Yes, it is reasonable, because the ME is 7.1% and 48% falls within the range of 53.8% to 7.1%.
Calculating the ME:

The sample proportion was 53.8%. This gives us
53.8% +/- 7.1%
To start you should represent CBX as x. so, an equation would be 92 = x + 4x + 12. This is the equation so, 92 is the total angle, and the 12x + 4 is the ABX part. So, once you solve the problem you should get CBX=76 and ABX=16
The sine is the opposite side / hypotenuse and the hypotenuse is the longest side. So the ratio must be less than 1, and as the lengths are positive the sine must be positive.
