PLEASE HELP!!!
Find sin D, sin E, cos D, and cos E. Write each answer as a fraction in simplest form.
Answer:
Here are what they equal in their simplest forms!
Step-by-step explanation:
Sin D & Cos E were originally equal to 13 -/3 over 26
-
Sin E & Cos D were originally equal to 13/26
-
Hope I was able to help!
Answer:
sin D = FE/DE = 13√3 /26 = √3 /2
sin E = DF/DE = 13/26 = ½
(sin E = cos D)
cos D = DF/DE = 13/26 = ½
cos E = EF/DE = 13√3 /26 = √3 /2
(sin D = cos E)

Write an equation that could be used to find the value of x using the interior angles of ∆ABD, then solve the equation.
Answer:
equation: 55 + (2x + 3) + 90 = 180
55 + 2x + 3 + 90 = 180
2x + 148 = 180
2x = 32
x = 16
Answer:
55 + 50 + 2x+3 + 2x+8 = 180
x = 16
Step-by-step explanation:
55 + 50 + 2x+3 + 2x+8 = 180
113 + 4x = 180
4x = 64
x = 16

Step-by-step explanation:
SE TIENE 45 NIÑOS Y 35 NIÑAS. DE LOS CUALES 60 VIVEN EN EL DISTRITO DE BREÑA. SI EL 30% QUE NO VIVEN EN BREÑA SON MUJERES. ¿QUÉ CANTIDAD SON VARONES?
Answer:
14 son varones
Step-by-step explanation:
Primero tenemos que sumar la cantidad de niños y niñas para saber cuantos hay en total
45 + 35 = 80
60 de ellos viven en el Distrito de Breña entonces los descontamos del total
80 - 60 = 20
Esto nos dice que 20 NO viven en Breña. Si 30% son mujeres quiere decir que el resto 70% son varones. Asi que multiplicamos los 20 por 70% en formato decimal que seria 0.70
20 * 0.70 = 14
Finalmente, podemos ver que 14 son varones viviendo fuera de Breña

4 cubed is 64
150 - 64 = 86
Have a great day <3
Answer:
86
Step-by-step explanation:
[tex]150 - (2 + x)^{3}[/tex]
x = 2
[tex]150 - (2 + 2)^{3}[/tex]
BEDMAS
(brackets)
⇒ [tex]150 - (2 + 2)^{3}[/tex]
⇒ 150 - [tex]4^{3}[/tex]
(exponents)
⇒ 150 - [tex]4^{3}[/tex]
⇒ 150 - 64
(subtraction)
⇒ 150 - 64
⇒ 86

Answer:
angles 5,6 are supplementary
angles 7 and 4 are vertical angles
(one solution of many)
Step-by-step explanation:
Lets start with supplementary angles. those are two angles that add up to 180 degrees or make a straight angle. Two angles that fulfill this statement are 5 and 6 because 5 and 6 make a straight angle.
Now lets do vertical angles. Vertical angles are angles that are opposite of each. They are made by intersecting diagonals. One pair of angles that fulfill this are angles 7 and 4. if you can tell, they are opposite of each other.
supplementary= 5 and 6
vertical= 7 and 4
have a wonderful day!

write f(x)=-(x+3)^2+8 in standard form
Answer:
f(x) = -x^2 -6x - 1
Step-by-step explanation:
Answer:
y=-x^2-6x-1
Step-by-step explanation:
f(x)=-(x+3)^2+8
f(x)=-(x+3)(x+3)+8
f(x)=-(x^2+3x+3x+9)+8
f(x)=-x^2-3x-3x-9+8
f(x)=-x^2-6x-9+8
f(x)=-x^2-6x-1
y=-x^2-6x-1
5 x +4+=34

How many solutions does the system have?
y=3x+3
y=−2x+3
choose 1 answer
A) Exactly one solution
B) No solutions
C) Infinitely many solutions
Answer:
A
Step-by-step explanation:
Given the 2 equations
y = 3x + 3 → (1)
y = - 2x + 3 → (2)
Substitute y = 3x + 3 into (2)
3x + 3 = - 2x + 3 ( add 2x to both sides )
5x + 3 = 3 ( subtract 3 from both sides )
5x = 0 , then
x = 0
Substitute x = 0 into (1)
y = 3(0) + 3 = 0 + 3 = 3
solution is (0, 3 ) → A

Answer:
arc MKL ≈ 19.02 m
Step-by-step explanation:
The figure shows angle KNL is the complement of angle KNJ, so is ...
∠KNL = 90° =∠KNJ
∠KNL = 90° -52° = 38°
We know that KM is a diameter, so arc MJK = 180°, and ...
arc MKL = 180° +38° = 218°
In radians, that angle measure is ...
218° × π/180° rad = 109π/90 rad
An arc length is given by the formula ...
s = rθ . . . . . where r is the radius and θ is the radian measure of the arc
For this problem, the radius is MN = 1/2MK = 5 m, and the length of arc MKL is ...
s = rθ
arc MKL = (5 m)(109π/90) = 109π/18 m
arc MKL ≈ 19.02 m
