Answer:
x = 8
y = 4 sqrt(3)
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp / hyp
sin 30 = 4/x
x sin 30 = 4
x = 4 / sin 30
x = 4 / ( 1/2)
x = 8
tan theta = opp /adj
tan 30 = 4/y
y tan 30 =4
y = 4 / tan 30
y = 4 / ( 1/ sqrt(3))
y = 4 sqrt(3)
Answer and Step-by-step explanation:
To solve, we need to use Trigonometric Functions.
These functions include Sine, Cosine, and Tangent.
- Each one has its own rule to follow when solving.
θ = Angle
sin(θ) = [tex]\frac{Opposite.Side}{Hypotenuse}[/tex]
cos(θ) = [tex]\frac{Adjacent.Side}{Hypotenuse}[/tex]
tan(θ) = [tex]\frac{Opposite.Side}{Adjacent.Side}[/tex]
For this problem, we will only be using the trigonometric functions of Sine and Tangent.
Start by finding x.
sin(30) = [tex]\frac{4}{x}[/tex]
Multiply x to both sides.
x × sin(30) = [tex]\frac{4}{x}[/tex] × x
x(sin(30)) = 4
Divide both sides of the equation by sin(30).
x(sin(30)) ÷ (sin(30)) = 4 ÷ (sin(30))
x = [tex]\frac{4}{sin(30)}[/tex]
Simplify in calculator.
x = 8
Now find the value of y.
tan(30) = [tex]\frac{4}{y}[/tex]
Multiply y to both sides.
y × tan(30) = [tex]\frac{4}{y}[/tex] × y
y(tan(30)) = 4
Divide both sides of the equation by tan(30).
y(tan(30)) ÷ (tan(30)) = 4 ÷ (tan(30))
y = [tex]\frac{4}{tan(30)}[/tex]
Simplify in calculator.
y = [tex]4\sqrt{3}[/tex]
x = 8
y = [tex]4\sqrt{3}[/tex]

What is a right-angled triangle?
A triangle in which one of the interior angles is 90° is called a right-angled triangle. The longest side of the right triangle, which is also the side opposite the right angle, is the hypotenuse and the two arms of the right angle are the height and the base.
According to the given problem,
Perpendicular = 8.8
Base = x
Let the Hypotenuse be h,
∅ = 72°
We know,
sin∅ = [tex]\frac{Perpendicular}{Hypotenuse}[/tex]
⇒ sin72 = [tex]\frac{8.8}{h}[/tex]
⇒ 0.95 = [tex]\frac{8.8}{h}[/tex]
⇒ 0.95h = 8.8
⇒ h = [tex]\frac{8.8}{0.95}[/tex]
⇒ h = 9.3
Now, applying Pythagoras theorem,
Hypotenuse² = Perpendicular² + Base²
⇒ 9.3² = 8.8² + x²
⇒ 9.3² - 8.8² = x²
⇒ x² = 9.05
⇒ x = √9.05
⇒ x = 3
Hence, we can conclude the value of x to be 3.

What are the coordinates of the point on the directed line segment from (-6, -1)(−6,−1) to (6, -9)(6,−9) that partitions the segment into a ratio of 3 to 1?
Given:
A segments is from (−6,−1) to (6, -9).
A point divides the line segment into a ratio of 3 to 1.
To find:
The coordinates of the points.
Solution:
Section formula: If a point divides a line segment in m:n, then
[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
The point divides the line segment in 3:1, so by using section formula, we get
[tex]Point=\left(\dfrac{3(6)+1(-6)}{3+1},\dfrac{3(-9)+1(-1)}{3+1}\right)[/tex]
[tex]Point=\left(\dfrac{18-6}{4},\dfrac{-27-1}{4}\right)[/tex]
[tex]Point=\left(\dfrac{12}{4},\dfrac{-28}{4}\right)[/tex]
[tex]Point=\left(3,-7\right)[/tex]
Therefore, the coordinates of the required point are (3,-7).

Answer:
Angle ECM is approximately 25.786°
Step-by-step explanation:
The given details are;
The horizontal base of the triangular prism ABCDEF = ABCD
AE = 17 cm = BE
M = The midpoint of AB
AB = 16 cm
BC = 30 cm
In a triangular prism, the angle EBC = 90°
Therefore;
[tex]\overline {CE}^2 = \overline {BE}^2 + \overline {BC}^2[/tex]
[tex]\therefore \overline {CE} = \sqrt{\overline {BE}^2 + \overline {BC}^2}[/tex]
CE = √(17² + 30²) = √1189
Similarly, we have;
[tex]\overline {CM}^2 = \overline {BM}^2 + \overline {BC}^2[/tex]
Where;
BM = AB/2
∴ BM = (16 cm)/2 = 8 cm
Therefore;
CM = √(8² + 30²) = 2·√241
By trigonometric ratio in the triangle formed by the points CEM, which is the right triangle ΔCEM, we have;
cos(∠ECM) = CM/EC
∴ ∠ECM = arccos(CM/EC)
Plugging in the values gives;
∠ECM = arccos((2·√(241)/√(1189)) ≈ 25.786°

En una sala de teatro havian 7 filas 23 sillas cada una acaban de quitar 8 de las sillas ¿cuantas sillas quedan?
Answer:
Quedan 153 sillas
Step-by-step explanation:
Primero sabemos que en una sala de teatro tenían 7 filas, y en cada una de esas filas habían 23 sillas.
Entonces, originalmente, el número total de sillas es 7 veces 23:
S = 7*23 = 161
Luego sabemos que quitan 8 de esas sillas, entonces el número de sillas que quedan es la diferencia entre el número original de sillas, 161, y 8, que nos da:
S = 161 - 8 = 153
Quedan 153 sillas

If we round up the 3/4 cup of sugar to 1 cup to make it easier, and then multiply by 2 because the 3/4 cup of sugar only makes half a dozen cupcakes, then we will get 2 cups of sugar which is an overestimate of how much is needed. If we multiply it again by 3 because he needs 3 times the amount of sugar, we get 6 cups of sugar because we rounded it up. Since we know 3/4 is less than 1, we can assume that 6 cups of sugar is more than needed.

On a coordinate plane, a parabola opens down. It goes through (negative 5, 0), has a vertex at (negative 2, 9), and goes through (1, 0).
Which statement about the function is true?
The domain of the function is all real numbers less than or equal to −2.
The domain of the function is all real numbers less than or equal to 9.
The range of the function is all real numbers less than or equal to −2.
The range of the function is all real numbers less than or equal to 9.
Answer:
the last one : the range of the function is all real numbers less than our equal to 9.
Step-by-step explanation:
it is a parabola that opens up only down. that means all the calculated y-values go deeper and deeper into lower and negative values the more right or left we go on the x-axis.
the maximum y-value we have at the vertex with y=9. no other x-value can generate a bigger y-value.
that's why the last answer option is right.
