Mhanifa please help! Find the missing side. Round to the nearest tenth
Answer:
12) x = 49.5
13) x = 8.5
14) x = 44.8
15) x = 4.6
Step-by-step explanation:
We can solve for the missing side lengths using trigonometry
Remember these are the trigonometric ratios
Sin = Opposite over Hypotenuse
Cos = Adjacent over Hypotenuse
Tan = Opposite over Adjacent
For #12
We can use trig ratio tangent as we are given an angle with a measure of 68° and its adjacent side length and we need to find the opposite side length. When dealing with opposite and adjacent we can use tan.
That being said we want to create an equation to solve for x
[tex]tan(68)=\frac{x}{20}[/tex]
Now we solve
* multiply each side by 20 *
[tex]20tan(68) = 49.5\\\frac{x}{20} 20=x\\[/tex]
we're left with x = 49.5
It seems that all of the problems are dealing with an angle, its opposite side and its adjacent side. So we will use the same trig ratio "tan" and process to solve for x.
For 13)
[tex]tan(62)=\frac{16}{x} \\[/tex]
*multiply each side by x*
[tex]xtan(62)=16[/tex]
*divide each side by tan(62)
[tex]\frac{xtan(62)}{tan(62)} =x\\\frac{16}{tan(62)} =8.5[/tex]
we're left with x = 6.5
For 14)
[tex]tan(15)=\frac{12}{x}[/tex]
multiply each side by x
[tex]xtan(15)=12[/tex]
divide each side by tan15
[tex]\frac{xtan(15)}{tan(15)} =x\\\frac{12}{tan(15)} =44.8[/tex]
we're left with x = 44.8
For 15)
[tex]tan(74)=\frac{16}{x}[/tex]
multiply each side by x
[tex]xtan(74)=16[/tex]
divide each side by tan(74)
[tex]\frac{xtan(74)}{tan74} =x\\\frac{16}{tan(74)} =4.6[/tex]
we're left with x = 4.6

Answer:
8
24
3
yes
Step-by-step explanation:
the original area of the figure is 4 · 2 which equals 8.
Since the dilation that is needing to be done is by a scale factor of 3 then all we need to do is multiply the original area by 3, which gives us the new area 24.
So because the only transformation was a dilation that didn't significantly change the figure then we can say that both figures are similar.
If a fair coin is tossed 8 times, what is the probability, to the nearest thousandth, of getting exactly 0 tails?

What is Coordinate System?Arrangement of reference lines or curves used to identify the location of points in space is called coordinate system.
Line x is parallel to line y.
Line z intersects lines x and y.
∠1+∠4=180 degree is always true.
∠5-∠7=0 is always true because the two angles are true.
z⊥y is sometimes true.
∠2≅∠8 is always true because the two angles are congruent.
∠2-∠3=∠1-∠4 will be sometimes true.
Hence, the ∠1+∠4=180 degree is always true, ∠5-∠7=0 is always true , z⊥y is sometimes true, ∠2≅∠8 is always true and ∠2-∠3=∠1-∠4 be sometimes true.

Which of the
following could define the function g? Explain your reasoning.
• Equation A: g(x) = 20 - (1.5)*
• Equation B: g(x) = 20. (2.5)*
• Equation C: g(x) = 10. (3.5)*
• Equation D: g(x) = 20 · (4.5)*
the following could define the function g: 20. (2.5)ˣ = g(x)
correct option: B
What is function?Exactly one element of Y is assigned to each element of X in a mathematical function from a set X to a set Y. Both the set X and the set Y are referred to as the function's domain and co-domain, respectively. The basic conception of functions was the relationship between fluctuating quantities and other variables.
h(x) = 20. 4ˣ (0, 20)
here, g(x) passes through the point (0, 20)
thus, g(x) = 20. aˣ
when x > 0, f(x) < g(x) < h(x)
hence a < 4
so, 20. (2.5)ˣ - 10. 2ˣ > 0
or, 20. (2.5)ˣ = g(x)
correct option: B

[tex]\triangle CAB\cong \triangle ONP[/tex]
Step-by-step explanation:
Triangles [tex]\triangle CAB[/tex] and [tex]\triangle ONP[/tex] share two corresponding angles and the inclusive side between them. This is known as ASA (angle-side-angle) and does prove congruence. Therefore, [tex]\triangle CAB\cong \triangle ONP[/tex].
The four proofs of congruence include SSS (side-side-side), SAS(side-angle-side), ASA (angle-side-angle) and AAS (angle-angle-side). No other pair of triangles demonstrate any of these.

Answer:
6
Step-by-step explanation:
To find the median you simply look for the number in the middle of the list.
In this particular case 1 and 11 are both the fifth number in the series of numbers. When this happens you have to add the two terms together (1+11) and divide by two (12/2)=6

Answer:
it's an equilateral triangle, so all the angles will be equivalent.
2x + 2x + 2x = 180
6x = 180
x = 30°
Answer:
30
Step-by-step explanation:
So, the solve this, lets first find the type of traingle it is.
Well, all the sides are equal, beign 3, so it must be a equalaterial triangle.
This means both the sides and angles will be the same.
Remember, there are 180 degrees in a triangle.
So we can think of it like this, since there are 3 angles, each being 2x:
6x=180 degrees
Now we can just get x alone by divide by 6:
x=30
So your answer is 30!

A textbook store sold a combined total of 411 psychology and history textbooks in a week. The number of history textbooks sold was 69 less than the number of
psychology textbooks sold. How many textbooks of each type were sold?
Answer:
Step-by-step explanation:
h and p are the number of history and psych textbooks, respectively.
store sold a total of 411 textbooks in a week.
h + p = 411
The number of history textbooks sold was 69 less than the number of psychology textbooks sold.
h = p - 69
Substitution
(p-69) + p = 411
2p = 411+69
p = 240
h = p-69 = 171
171 history books and 250 psych books

Will mark brainliest please help ASAP Complete the square to find the vertex of this parabola x^2+14x-y-14=0
Answer:
the vertex is (-7, -63)
Step-by-step explanation:
x^2 + 14x - y - 14 = 0
x^2 + 14x = y + 14 (to isolate the x)
x^2 + 14x + 49 = y + 14 + 49
(x+7)^2 = y + 63
now we convert to vertex form, which is y = a(x – h)2 + k :
(x+7)^2 = y + 63
y = (x+7)^2 - 63
The vertex in vertex form is shown as (h, k) from y = a(x – h)2 + k, so in this case, h = -7 and k = -63. H is the x-coordinate as shown while k is the y-coordinate. Thus, the vertex is (-7, -63)

Slope-intercept form is given by [tex]y=mx+b[/tex].
Since Farmer Coraz purchases 10 items every month, he will have [tex]10\cdot x[/tex] items every [tex]x[/tex] months. Since he initially starts out with 0 items, at [tex]x=0[/tex], y is also equal to 0, and thus we have the final equation:
[tex]y=10x\text{ or }y=10x+0[/tex]
*Note: while slope-intercept form is [tex]y=mx+b[/tex], since the value of [tex]b[/tex] is 0, it is possible to omit it from the final equation and both answers should receive credit.
