Hello!
This is a question relating trigonometry to unknown sides.
Here we can use the law of sines, which state that if a triangle is a right triangle, the ratio between a side and the sin of its opposite angle will be equal to any other ratio of the same type.
This means that we can set up this equation.
[tex]\frac{17}{sin(90)}=\frac{AC}{sin(38)}[/tex]
[tex]AC=17sin(38)[/tex]
Be sure to be on degrees if you're on a calculator.
[tex]AC=10.47[/tex]
Hope this helps!

(2) Parv has a $50 gift card. He uses the gift card to buy a pack of games
for $9.99. He also wants to buy some movies (n). Each movie costs
$3.99. Which inequality describes how many movies Parv can buy?
Answers
Answer:
$50 - $9.99 = $40.01
$40.01 ÷ $3.99 = 10
so the answer is 10
Step-by-step explanation:
if thats not whats being asked sorry
Inequality shows a relationship between two numbers or two expressions.
The inequality describes the number of movies Parv can buy.
9.99 + 3.99x ≤ 50
Where x is the number of movies.
The number of movies Parv can buy is 10.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal= ≥
We have,
Gift card = $50
Cost of a pack of games = $9.99
Cost of each movie = $3.99
x = number of movies
The inequality describes the number of movies Parv can buy.
9.99 + 3.99x ≤ 50
Where x is the number of movies.
Solve for x.
9.99 + 3.99x ≤ 50
Subtract 9.99 on both sides.
3.99x ≤ 50 - 9.99
3.99x ≤ 40.01
Divide both sides by 3.99
x ≤ 40.01/3.99
x ≤ 10
This means the number of movies Parv can buy is 10.
We can cross-check.
9.99 + 3.99 x 10 ≤ 50
9.99 + 39.9 ≤ 50
49.89 ≤ 50
Thus,
The number of movies Parv can buy is 10.

Dos libras de carne de res y dos de chivo cuestan $334 pesos, si duplico la libra de carne de res y una libra de chivo cuestan $420 pesos. ¿Cuál es el precio por libra de cada producto?
Answers
Answer:
El precio por libra de la carne de res es $84.33 y el precio por libra de chivo es $82.67.
Step-by-step explanation:
Con la información proporcionada puedes escribir las siguientes ecuaciones:
2x+2y=334 (1)
4x+y=420 (2), donde:
x es el precio por libra de carne de res
y es el precio por libra de chivo
Primero, puedes despejar x en (1):
2x=334-2y
x=334/2-2y/2
x=167-y (3)
Ahora, debes reemplazar (3) en (2) y despejar y:
4(167-y)+y=420
668-4y+y=420
668-3y=420
668-420=3y
248=3y
y=248/3
y=82.67
Finalmente, puedes reemplazar el valor de y en (3) para encontrar el valor de x:
x=167-y
x=167-82.67
x=84.33
De acuerdo a esto, la respuesta es que el precio por libra de la carne de res es $84.33 y el precio por libra de chivo es $82.67.

Hey! Could someone explain to me how to find the perimeter of this figure? It would be greatly appreciated!
Answers
Answer:
3/2 pi + 12
Step-by-step explanation:
In this figure, we have 4 sides and one curve. The total length of the four sides is 3 x 4 = 12. To find out the length of the curve, we need to find the angle of the top figure. Since it is next to a square, that means the angle that is farthest from the curve is 90 degrees.
The formula for finding an angle of a curve is n/360 x 2 pi x radius, where n is the angle.
The radius of the arc is 3, because at the bottom we see the width of the figure is 3.
Substituting our known values, we have 1/4 x 2 x pi x 3 = 6 x 1/4 x pi = 3/2 x pi.
Therefore, our answer is 3/2 pi + 12

A maple tree is 16 yards tall and its shadow is 12 yards long. A nearby observation tower is 12 yards tall. How long is the observation tower's shadow? Write your answer as a whole number or a decimal. Do not round.
Answers
Answer: 9 yards
Step-by-step explanation:
Given
The maple tree is 16 yards tall and its shadow is 12 yards tall
Suppose the angle made by the maple tree is x
[tex]\Rightarrow \cos x=\dfrac{12}{16}[/tex]
For the tower also, the angle made by the tower and its shadow is x
Suppose the length of the shadow is y
[tex]\Rightarrow \cos x=\dfrac{y}{12}[/tex]
Substitute the value of [tex]\cos x[/tex]
[tex]\Rightarrow \dfrac{y}{12}=\dfrac{12}{16}\\\\\Rightarrow y=9\ \text{yards}[/tex]

Step-by-step explanation:
90 degrees is a right angle, which is just straight up, and has a. square symbol. So, we can use that to compare the answers. Anything over 90 degrees would have its angle tilt to the left.

Step-by-step explanation:
We solve using Pythagoras Theorem. Pythagoras Theorem is used to solve for the missing side of a right angled triangle.
The formula for Pythagoras Theorem =
c² = a² + b²
c = √a² + b²
Where c is the longest side
From the above diagram, we are looking for c
c = ?
a = 6
b = 8
Hence,
c = √6² + 8²
c = √36 + 64
c = √100
c = 10
Therefore, side c = 10

Answer:
[tex]Total = 625x^3 + 125x^2 + 125x[/tex]
Step-by-step explanation:
Given
[tex]Flowers = 25x^2 + 5x + 5[/tex]
[tex]Unit\ price = 5x[/tex]
Required
The total price for 5 days
First, calculate the total for a day.
[tex]1\ day = Unit\ price * Flowers[/tex]
[tex]1\ day = 5x * (25x^2 + 5x + 5)[/tex]
Open bracket
[tex]1\ day = 125x^3 + 25x^2 + 25x[/tex]
For 5 days, the total will be.
Total = days * sales of a day
So, we have:
[tex]Total = 5 * [ 125x^3 + 25x^2 + 25x][/tex]
[tex]Total = 625x^3 + 125x^2 + 125x[/tex]
Find the value of y that makes 120y a perfect square
Answers
Step-by-step explanation:
y = 30
120y = 120×30 = 3600
√3600 = 60
The value of y is 60 which makes 120y a perfect square.
What is a perfect square?A perfect square is a number that represents the square of a natural number.
For example 9,16,36,64,121 etc
Here given that we have to calculate the value of y for which 120y will be a perfect square.
so 120y = n² where n is the natural number
For calculating the value of y first factorize 120
120= 2*2*2*3*5
= 2² * 2*3*5
=4 *30
from the above, it is clear that 120 can be written as 4*30 where 4 is a perfect square but 30 is not a perfect square.
So if we multiply 30 by 120 then the product has 2²*30² which will be a perfect square.
Therefore the value of y is 30 for which 120*30=n² where n=60.
