We know that In right angle triangle c^2 = a^2 + b^2.
19^2 = 3^2 + b^2
b = (361 - 9)^1/2 = 18.761663039294
Now for angles
sin(A) = a/c = 3/19
A = sin{-1}(3/19) = 9.0847202873911
A = 9.0847202873911
sin(B) = b/c = 18.761663039294 / 19
B = sin{-1}(18.761663039294 / 19) = 80.915279712614
B = 80.915279712614

Answer:
$2.69
Step-by-step explanation:
The prices of the 3 books are:
$2.50, $4.95, $6
The total is $2.50 + $4.95 + $6 = $13.45
The sale is 20% off.
20% of $13.45 =
= 0.2 * $13.45
= $2.69
Answer: You will save $2.69.
Answer:
Total eclipse was 
minutes longer than in 2005.
Step-by-step explanation:
It is given in the question that total eclipse in 2003 lasted 
minutes and in 2005 it lasted 3/8 of a minute.
We have to calculate how much longer did it last in 2003.
So we have to subtract the duration in 2003 by duration in 2005
Total time taken in 2003- total time taken in 2005
minutes
