I believe your answer is D
sorry if im wrong
Step-by-step explanation:
If it was one year it would be 2200 and you just keep adding 200 for each year.
The total cost of the book would be:
12.50* 0.8= 10
The total cost of the book would be $10.00
Answer:
I think it's the last one. Sorry if I'm wrong
1. By the Law of Sines, you have:
SinA/a=SinB/b=SinC/c
2. You don't need the fraction SinC/c, so you can eliminate it. Then:
SinA/a=SinB/b
A=40°
a=19
B=m∠b
b=13
3. When you substitute this values into SinA/a=SinB/b, you obtain:
SinA/a=SinB/b
Sin(40°)/19=SinB/13
SinB=13xSin(40°)/19
m∠b=SinB^-1(13xSin(40°)/19)
m∠b=26.1°
Therefore, the answer is: 26.1 degrees.
