Answer:
[tex]\sin{72^\circ}[/tex]
Step-by-step explanation:
In a right triangle, the two acute angles are complementary--they add up to 90 degrees.
Cosine is defined as the adjacent side divided by the hypotenuse. In the attached picture, [tex]\cos{18^\circ}=\frac{a}{h}[/tex].
The other acute angle is 90 - 18 = 72 degrees. Looking at just that angle, side a is the opposite side. So the ratio a/h is opposite over hypotenuse -- the sine ratio.
Therefor, [tex]\cos{18^\circ} = \sin{72^\circ}[/tex]

solve for x round to nearest tenth
Answer:
33.3
Step-by-step explanation:
tan A = opp/adj
tan 39° = 27/x
x tan 39° = 27
x = 27/(tan 39°)
x = 33.3

Perimeter = 30 in.
Area = ?
Answer:
56
Step-by-step explanation:
the length of the missing side is 7
so 7 x 8 = 56
To find the missing side:
You must add 8 + 8 = 16
Subtract 16 from the total perimeter = 14.
Divide 14 by 2 = 7 you divide by two since there are two missing lengths and when you add them they have to equal to 14.

Answer:
29.4
Step-by-step explanation:
mC = 180 - 46 - 105 = 29
By Law of Sines: c/sin C = a/sin A
19.8/sin 29° = a / sin 46°
19.8/0.484 = a/0.72
a = 29.45 ≈ 29.4
The radius of a cylindrical construction pipe is 3.5ft . If the pipe is 38ft long, what is its volume? Use the value 3.14 for (pie symbol) , and round your answer to the nearest whole number. Be sure to include the correct unit in your answer.
Answer:
1462 cubic ft
Step-by-step explanation:
The volume of a cylinder can be found using the equation [tex]\pi r^{2}h[/tex]=V. The radius is 3.5 ft and the height is 38ft.
[tex](3.14)(3.5^{2})(38)[/tex]=V
(3.14)(12.25)(38)=V
1461.67=V and rounded to the nearest whole numbe, 1462 cubic ft=V

24 is 44% of what number?
yall i have exams tomorrow and i have no clue how to do percentages TwT helppp
Answer:
24 is 44% of 54.55
Step-by-step explanation:
24 ÷ 44% = y ÷ 100%
Solve for y - To do so, we will use cross multiplication.
44y = 24 × 100
44y = 2400
y = 2400 ÷ 100
y = 54.55

Brianna's teacher asks her which of these three expressions are equivalent to each other. which is equivalent
Answer:
Please specify what the three expressions are.
Step-by-step explanation:
From what I understand, you need to set the expressions equal to each other. For instance, if one is 2(x-3) and the other is 2x-6, you could write it as:
[tex]2(x-3)=2x-6[/tex]
Then, by evaluating it, you would get:
[tex]2x-6=2x-6[/tex] by distribution over subtraction.
[tex]2x-6+6=2x-6+6[/tex] by the additive property of equality
[tex]2x=2x[/tex] Simplify.
[tex]x=x[/tex] by the reflexive axiom.
Since x will always equal itself, 2(x-3) and 2x-6 are equivalent.
Therefore, if the expressions, once set equal to each other, result in the equation x=x, or any other expression in which one quantity equals itself, the two expressions are equal.
Sorry I could not be of more help, but you did not specify what the expressions were.

Ainsley works for the owners of a bookstore. Her starting salary was 24,500, and she gets a 3% raise each year. Write an equation in function notation to represent subsidy’s salary as a function of the number of years she has been working at the bookstore. What will Ainselys salary be when she begins her fourth year working at bookstore?
Answer:
if x is the number of years she is working that the equation would be: 24,500+x*((3/100)*24,500)
Step-by-step explanation:
For her 4th year x would be 4, so for the equation above x=4:
24500+4*((3/100)*24500)=27440
