Answer:
a. <B = 53°
b. BC = 14
c. x = 14
Step-by-step explanation:
Sine(theta) = Opp/HypCosine(theta) = Adj/HypTan(theta) = Opp/Adja. <B = ?
Use Sine.
Sine(<B) = 12 /15
<B = Sin^-1(12/15)
<B = 53.13
<B = 53°
b. BC = ?
Either use Sine(<A) = BC/16 or Cosine(<C) = BC/16
Will be using Cosine.
Cosine(<C) = BC/16
Cosine(30°) = BC/16
BC = 16 * Cos(30°)
BC = 13.856...
BC = 14
c. x = ?
Looking at the triangle. The triangle is isosceles which mean two side angle or side length are the same.
x = 14
Answer:
A: 53.13
B:13.86
C: 14
Step-by-step explanation:
A can be found by using the trigonometric ratio Sin.
Sin=
[tex] \frac{opp}{hyp} [/tex]
And we have our opposite side and hypotenuse. so insert it:
Sin=12/15
Therefore use sin inverse and input that fraction
[tex]sin { }^{ - 1} ( \frac{12}{15} )[/tex]
=53.13010235
Rounded off to two decimals
=53. 13
B can be found using sin again. Since we know that Sin is opp/hyp and we have the hyp, we are now looking for the opp.
So use Sin(60)=BC/16
Multiply 16 on both sides to get: 16Sin(30)=BC
13.85640646=BC
rounded off to two decimals:
13.86
C can be found using Tan. Tan is opp/adjacent
We have the adjacent and we are looking for the opposite.
So use:
tan(45)=X/14
Multiply 14 on both sides
14tan(45)=X
14=X
Hope that helps!

9.3 x and 60 degrees are all related to the Tangent of L or Tan(L) as you would find it on your calculator.
Givens
Opposite = 9.3Adjacent = xTheta = 60Formula
Tan(60) = opposite / Adjacent Substitute Values
Solution
Tan(60) = 9.3 / x Multiply both sides by x
x*Tan(60) = x * 9.3 /x
x* Tan(60) = 9.3 Divide both sides by Tan(60)
x * Tan(60) / Tan(60) = 9.3/Tan(60)
x = 9.3 / 1.7321

Answers
Answer:
The third measurement is 62°
Step-by-step explanation:
Hey there! Please take a look at the explanation for clear understanding to the answer and also let me know in comment if you have any doubts!
Euclidean TriangleThe theorem regarding it states that, sum of all 3 interior angles must equal to 180°.
That means, we will have this equation:
[tex]\displaystyle \large{28^{\circ} + 90^{\circ} + x=180^{\circ}}[/tex] because we know two interior angles and one missing angle - sum of them equals to 180 degrees.
Then we solve for x-term to find the third measurement!
[tex]\displaystyle \large{118^{\circ}+x=180^{\circ}}[/tex]
Subtract both sides by 118 degrees.
[tex]\displaystyle \large{118^{\circ}-118^{\circ}+x=180^{\circ}-118^{\circ}}\\\\\displaystyle \large{x=62^{\circ}}[/tex]
Henceforth, the third measurement is 62°

What are possible coordinates of point F if ADEF is
congruent to AABC?
(-1,4)
(4,-1)
(0,-1)
(-1,0)
Answers
Answer:
(-1;4)
Step-by-step explanation:
as the triangles are congruent
The coordinate of point F is (1-, 4). Therefore, option A is the correct answer.
What is coordinate plane?A coordinate plane is a two-dimensional surface formed by two number lines. It is formed when a horizontal line (the X-axis) and a vertical line (the Y-axis) intersect at a point called the origin. The numbers on a coordinate grid are used to locate points.
From the given graph, the coordinate points are A(-5, 0), B(-5, -5) and C(2, -5).
Here, ΔABC and ΔDEF are congruent triangles.
So, the coordinate of point F are (1-, 4)
Therefore, option A is the correct answer.

What is the cost of the hot dog?
What is the cost of one hamburger?pleaseeeee hellpppppp
Answers
Answer:
1 hot dog = $1.50 each
1 hamburger = $1.75 each
Step-by-step explanation:
Answer:
The prices must be $1.50 and $1.75
Step-by-step explanation:
For instance, seven hot dogs and two hamburgers cost $14: 7D+2B=14
We also know that two hot dogs and seven hamburgers cost $15.25: 2D+7B=15.25
Now, if we combine these two equations, we have a system where EVERYTHING has to be true at the same time
7D+2B=14
2D+7B=15.25
From here there are a couple trick you should know to solve a system of equation, especially substitution and elimination. I see a coefficient of 2, so I'd rather use substitution by dividing the entire first equation in half:
3.5D+B=7
Now I'll solve for B
B=7-3.5D
Now that I've solved for a variable, I can substitute the solution into the other equation
2D+7( B )=15.25
becomes
2D+7(7-3.5D)=15.25
Now I can distribute and solve for D:
2D+49-24.5D=15.25
22.5D=33.75
D=1.5
Now we can replace D from either (or both) of our original equations and see what B has to be
7(1.5)+2B=14
10.5+2B=14
2B=3.5
B=1.75
2(1.5)+7B=15.25
3+7B=15.25
7B=12.25
B=1.75
The prices must be $1.50 and $1.75. The most important part of all this is setting up the equations, the rest is just being careful with your calculations.

PLEASE HELP!!!!!!!!!!!!!!!!!!!!!
Answers
Step-by-step explanation:
the last 2 answer options are completely useless and outright nonsense, because all limits are going against +4.
so, an asymptote at x = -4 is not an option anywhere.
g(x) is always y, and the limit of the function is the limit of the y values.
we just evaluate for what x value is then y reaching that limit. but the sign of the y limit has no direct impact on the sign of the x value.
it is true that the case x = -4 needs to be checked too, but it turns out this just delivers g(-4) = 0.
now, about x = 4 :
when coming from the left side of +4 (increasing x), what is the sign of the function ?
we can simply use x = 3 to test this :
g(3) = 2(3+4)²/(3² - 16) = 2×49/-7
so, it is negative.
that means when getting closer and closer to +4 coming from that side we what get negative values, and the limit is -infinity.
when coming from the right side of +4 (decreasing x), what is the sign of the function ?
we can simply use x = 5 to test this :
g(3) = 2(5+4)²/(5² - 16) = 2×81/9
so, it is positive.
that means when getting closer and closer to +4 coming from that side we what get positive values, and the limit is +infinity.
so, the second answer option is correct.
because of these y limits, there is a vertical asymptote at x = 4 that kind of "connects" -infinity and +infinity in y direction at that location and symbolizes the limits of y.

Now, we know that we have 3 drama movie choices...so the chance we will choose drama is 3/12, but we are not finding that. We want the chance she will NOT choose drama, so that would be 9/12.
*Since the chance she will choose drama is 3/12, the chance she will not choose is 9/12. 9+3 is 12, the total amout.*
