Sin(30) * 12 = AD
6 = AD
Hope this helps!
Find AD.

[tex] \sf c. \: 6 \: m[/tex]
[tex] \sf d. \: 6 \sqrt{3} [/tex]
____________________
Solution :-Given Information :-∠DCB = 30°∠BDC = 90°∠ABC = 90°BC = 12 mTo Find :-The Length of AD Calculation :-Here, Sin θ is 30°
Sin = [tex] \bf \frac{perpendicular}{hypotenuse} [/tex]
Here, θ is 30°
Substituting the values, We get,
∴ Sin ( 30 ) = [tex] \sf \frac{AD}{BC} [/tex]
Substituting the value of BC as 12, We get,
⇒ Sin ( 30 ) = [tex] \sf \frac{AD}{12} [/tex]
Transposing 12 to Left Hand Side, We get,
⇒ Sin ( 30 ) × 12 = AD
Calculating further, We get,
⇒ AD = 6 m
∴ AD = 6 m
____________________Final Answer :-The Length of AD is 6 m

Answer:
[tex]\bold{y=3x-11}[/tex]
Step-by-step explanation:
Begin with the equation [tex]y=mx+b[/tex]. Let's first find [tex]m[/tex].
For each time [tex]x[/tex] increases by 2 (the rows skip by 2), [tex]y[/tex] increases by 6. Since the relationship is linear, if [tex]x[/tex] were to increase by just 1 (half of 2), [tex]y[/tex] would increase by 3 (since we halve each component). Therefore, [tex]m=3[/tex].
To find [tex]b[/tex] (the y-intercept), we plug in the first value of [tex]x[/tex] we are given and notice the result. In this case, [tex]4 *3=12[/tex]. However, the first value of [tex]y[/tex] is 1, so we must subtract 11 so that the first term is 1. Hence, [tex]y=3x+11[/tex].

Answer:
x = 148
Step-by-step explanation:
vertical angles are congruent
the angle with a measure of 148° and the angle labeled "x" are vertical angles.
Hence, x = 148
Answer:
x=148 because the opposite angles are equal
also, the rest of the smaller angles are both 32 degrees if you need them
you can check because 148+148+32+32=360

Given g(x) = -x + 5, solve for x when g(x) = 0
Answers
Answer:
x = 5
Step-by-step explanation:
Given g(x) = - x + 5 and g(x) = 0 , then equate the right sides
- x + 5 = 0 ( subtract 5 from both sides )
- x = - 5 ( multiply both sides by - 1 )
x = 5

if 2(a-3)=3(a+2) then a =6
Answers
Answer:
No, a=-12
Step-by-step explanation:
To solve this, you have to use the distributive property. 2(a-3) is going to be equal to 2a-6 and 3(a+2) is going to be equal to 3a+6. This will make the equation 2a-6=3a+6. You add 6 from both sides to isolate a. This will make the equation 2a=3a+12. Subtract 3a from both sides to get -a=12. You want to isolate a so you have to divide both sides by -1. This will make the equation a=-12.

Answers
Answer:
33 bags and 4 cookies remaining
Step-by-step explanation:
268/8=33.5
Now do reverse to find the remainder ammount of cookies
33*8=264
Since each bag contains 8 cookies, there is...
33 bags and 4 cookies remaining
to find the remainder ammount of cookies you subtract 268-264 and you have 4 cookies left over.

Answer:
I'm pretty sure it's either 3.1 or 4.1
Step-by-step explanation:
Answer:
x = (571 ± √186217) / 18
x ≈ 7.74840677368558702303.. or 55.69603767075885742140..
x ≈ 7.75 or 55.70
Step-by-step explanation:
y = -9x² + 571x – 3884.
x = (-b ± √b² – 4ac) / 2a
x =
(-(571) ± √((571)² – 4((-9) × (-3884))) / 2(-9)) →
(-571 ± √(326041 – 4(34956))) / -18) →
(-571 ± √(326041 – 139824)) / -18) →
(-571 ± √(186217)) / -18 →

Answers
Hello, I Am BrotherEye
Answer:
Median = 46.5
Minimum = 32
Maximum = 62
Lower quartile = 38
Upper quartile = 59
Step-by-step explanation:
Before we can proceed to solving any of these, it is best you arrange your data first from least to greatest
32 34 37 39 41 45 48 53 58 60 61 62
First we have the median. The Median is the middle value. In this case we an even number of data, which is 12 data points. The middle value of the data would be found in between the 6th and 7th data point:
45 and 48
To get the middle value, you need to solve for the value that is in the middle of 45 and 48 by getting the sum of both numbers and dividing it by two.
45 + 48 = 93
93 ÷ 2 = 46.5
The minimum and maximum value is merely the least and greatest number.
Here we have:
Minimum = 32
Maximum = 62
To get the lower and upper quartiles, just remember that quartiles divide the data into 4 equal parts. All you need to do is find the value that is in between each quarters of the data:
Q1 (Lower) Q2(Median) Q3(Upper)
32 34 37 | 39 41 45 | 48 53 58 | 60 61 62
Like the median, we will find the value that comes in between each quarter.
Q1
37 + 39 = 76
76 ÷ 2 = 38
Lower quartile = 38
Q3:
58 + 60 = 118
118 ÷ 2 = 59
Upper quartile = 59
Answer:
median - 46.5
Lower quartile - 38
Upper quartile - 59
Maximum - 62
Minimum - 32

b = base
c = hypotenuse

==========================================================
It might help to draw a triangle to represent what's going on. See the diagram below.
Let's call the triangle ABC. We'll place point A at the 90 degree angle, so it's at the base of the tower. Place point B where the knight is located. Point C is the location of the window in the tower.
The knight is 15 feet away from the base, meaning AB = 15. With respect to the reference angle (B = 60), side AB = 15 is the adjacent side. The length of the ladder BC is the unknown hypotenuse. We'll call this x for now.
We'll use the cosine rule to connect the adjacent and hypotenuse.
cos(angle) = adjacent/hypotenuse
cos(B) = AB/BC
cos(60) = 15/x
x*cos(60) = 15
x = 15/cos(60)
x = 30
Your calculator needs to be in degree mode.
Because x = 30, we conclude that the ladder needs to be BC = 30 feet long.
Side note: For any special 30-60-90 right triangle, the hypotenuse is always twice as long compared to the shorter leg.

What is Unit conversion?The same attribute is expressed using a unit conversion, but in a different unit of measurement.
For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles.
Given:
John is 4 feet 8 inches tall.
= 4+ 8(0.0833333)
= 4+ 0.666667
= 4.6666667 feet
Mark, is 6 feet 4 inches tall
= 6 + 4 (0.0833333)
= 6+ 0.33333
= 6.3333 feet
So, Mark is = 6.33333- 4.66667 = 1.66663 feet taller
Hence, Mark is 1.66663 feet taller than John.
