If you would like to find the unit rate, you can calculate this using the following steps:
$11.49 ... 3 packages
$x = ? ... 1 package
11.49 * 1 = 3 * x
11.49 = 3 * x /3
x = 11.49 / 3
x = $3.83
The correct result would be $3.83.
Answer:
- a = 1.11
- B = 105.4°
- c = 2.95
Step-by-step explanation:
B = 180 -A -C = 105.4 . . . . sum of angles in a triangle is 180°
__
The missing side lengths can be found from the Law of Sines:
a/sin(A) = c/sin(C)
a = c·sin(A)/sin(C) = 2.46·sin(21.2°)/sin(53.4°) ≈ 1.11
Likewise, ...
b = c·sin(B)/sin(C) = 2.46·sin(105.4°)/sin(53.4°) ≈ 2.95
