Answer:
csc (- 30)° = - 2
Step-by-step explanation:
Using the trigonometric relationship
csc x = 
and the exact value sin30° = 
sin(- 30)° = - sin30° = - , thus
csc (- 30)° = 
= - 2
1 year=$50
1 movie=$2
25 movies×$2=$50
1 year=$50
$50+$50=$100
Well, it's SMALLER by 100, because 0.001 times 100 = 0.1 ;-)
I hope I helped! =D
Answer:
The answer to your question is the letter B) 2.6 feet
Step-by-step explanation:
Data
angle = Ф = 78°
Opposite side = 12 ft
Adjacent side = ?
To solve this problem use trigonometric functions. The trigonometric function that relates the Opposite side and the adjacent side is tangent.
tan Ф = Opposite side / Adjacent side
- Solve for Adjacent side
Adjacent side = Opposite side / tanФ
-Substitution
Adjacent side = 12 / tan 78
-Simplification
Adjacent side = 12 / 4.7
-Result
Adjacent side = 2.55 ≈ 2.6 ft
If you would like to simplify <span>4(x + 5) - 2(x - 3), you can do this using the following steps:
</span>4(x + 5) - 2(x - <span>3) = 4x + 4 * 5 - 2x + 2 * 3 = 2x + 20 + 6 = 2x + 26
</span>
If you would like to simplify <span>4(x - 5) - 2(x - 3), you can do this using the following steps:
</span>4(x - 5) - 2(x - <span>3) = 4x - 4 * 5 - 2x + 2 * 3 = 2x - 20 + 6 = 2x - 14</span>
