Both A and B are possible.
Step-by-step explanation:
It's both!
This is a might tricky. First you have to find the altitude. You have to determine if this is a real triangle.
Sin(22) = opposite / hypotenuse. The hypotenuse = 111. The angle is 22
opposite = hypotenuse * sin(22)
opposite = 111 * sin(22)
opposite = 41.58 and this is the altitude.
What have you learned?
Since 42 is larger than 41.58 you have 2 solutions to the triangle. One of the angles is acute, and the other one is obtuse. They are supplementary angles.
Sin(C) / c = Sin(A) / a
Sin(C) = c * Sin(22) / 42
Sin(C) = 111*sin(22)/ 42
Sin(C) = .99003
Sin(C) = 81.9
So that's your first answer. The second answer comes from Finding the supplement to this angle
supplement + 81.9 = 180
supplement = 180 - 81.9
supplement = 98.1

Answer:
[tex]\sf\Huge\boxed{C.40}[/tex]
Step-by-step explanation:
Hello There!
Remember: sum of interior angles of a triangle = 180
so to find x we use this equation
180 = 90 + 7x + 5 + 9x + 5 ( the little square in the triangle indicates that the angle is a right angle. right angles have a measure of 90 so that's where the 90 came from.)
now we solve for x
step 1 combine like terms
90 + 5 + 5 = 100
7x + 9x = 16x
now we have 180 = 16x + 100
step 2 subtract 100 from each side
180 - 100 = 80
100 - 100 cancels out
now we have 80 = 16x
step 3 divide each side by 16
80/16 = 5
16x/16=x
we're left with x = 5
Finally we plug in 5 into x for angle a
7(5)+5
7*5=35
35+5=40
so we can conclude that the measure of angle A is 40 degrees
A 5m ladder reaches 4.2m up a wall. What angle does the ladder make with the wall
Answer:
57.14°
Step-by-step explanation:
A 5m ladder reaches 4.2m up a wall. What angle does the ladder make with the wall?
We solve the above question using the Trigonometric function of Sine
= sin theta = Opposite/Hypotenuse
Opposite = Length of the wall = 4.2m
Hypotenuse = Length of the ladder = 5m
Theta = Angle formed = x
Hence,
sin x = 4.2m/5m
x = arc sin(4.2m/5m)
x = arc sin(0.84)
x = 57.140119621°
Approximately = 57.14°

A parabola is defined as all points equidistant from a given directrix and focus true or false
False. A parabola is not defined as all points equidistant from a given directrix and focus.
A parabola is a conic section defined as the set of all points that are equidistant from a fixed point called the focus and a fixed line called the directrix. In other words, for any point on a parabola, the distance to the focus is equal to the perpendicular distance to the directrix. This property is known as the geometric definition of a parabola.
The focus and directrix are essential elements in defining a parabola, but they do not solely define it. The shape of a parabola is determined by the distance between the focus and the directrix. Varying this distance results in different sizes and orientations of parabolas.
The specific equation of a parabola incorporates the coordinates of the focus, the directrix, and a parameter called the focal length to precisely describe its form. False is the answer.

A recipe needs 4/5 cup of butter for every 2 cups of flour. If you plan to use 3 cups of flour, how much butter will you need?
Answer:
0.4 cups of flower (2/5)
Good luck!!
Answer:
1 1/5 cups
Step-by-step explanation:
Write and solve an equation of ratios here. Let x be the amount of butter needed if 3 cups of flour are used. Then, comparing the quantities of butter first (in the first column) and the quantities of flour second, we get the ratio
x 3 cups
------------- = -------------
(4/5) cup 2 cups
Cross-multiplying, we get:
2x = 12/5, or x = 6/5
You'll need 6/5 cups of butter, or 1 1/5 cups, if you're using 3 cups of flour.

Step-by-step explanation:
The three interior angles in a triangle will always add up to 180°.
Therefore
[tex]59+(6x-10)+59=180\\(59+59-10)+6x=180\\108+6x=180\qquad|\text{subtract 108 from both sides}\\10-10+6x=180-108\\6x=72\qquad|\text{divide both sides by 6}\\\dfrac{6x}{6}=\dfrac{72}{6}\\\boxed{x=12}[/tex]
Answer:
Option C
The value of x is 12°
Step-by-step explanation:
Here, we know that in a Triangle The sum of all three angles is 180°.
Now,
59° + 59 + (6x - 10)° = 180°
118° + 6x - 10° = 180°
6x + 108° = 180°
6x = 180° - 108°
6x = 72°
x = 72° ÷ 6
x = 12°
Thus, The value of x is 12°

Lines a b and c are parallel and cut by a transversal. Angles 1 to 5 are labeled. Angle 1 is above line a to the left of the transversal. Angle 2 is below line a to the left of the transversal. Angle 3 is above line b to the right of the transversal. Angle 4 is below line b to the right of the transversal. Angle 5 is below line c to the right of the transversal.
m∠4=48°

The Gotemba walking trail up Mount Fuji is about 9 kilometres (km) long. Walkers need to return from the 18 km walk by 8 pm. Toshi estimates that he can walk up the mountain at 1.5 kilometres per hour on average, and down at twice that speed. These speeds take into account meal breaks and rest times. Using Toshi's estimated speeds, what is the latest time he can begin his walk so that he can return by 8 pm?
Answer:
He must start his journey by 11 AM
Step-by-step explanation:
Speed of Toshi while walking up the mountains is 1.5 kilometres per hour
Speed of Toshi while walking down the mountains = 2 * Speed of Toshi while walking up the mountains = 3 kilometres per hour
Time taken to travel 9 Km in the upward direction by Toshi = 9 Km/1.5 kilometres per hour = 6 hours
Time taken to travel 9 Km in the downward direction by Toshi = 9 Km/3 kilometres per hour = 3 hours
He will take total 6 hours + 3 hours = 9 hours to travel 18 Km distance
Thus, He must start his journey by 11 AM

13. Lastly I hope you have a good Day and I hope you Try staying focus I believe In you :)
-plug in earbuds or put on headphones, you dont have to play/listen to anything, but it helps block out noise
-maybe set a small goal for yourself, where if you get a class or quiz or whatever done, you go do something else that you enjoy for a few minutes and think of a new goal for the next class.
-sometimes actually playing music tends to help! at least to me
-it can be hard, but try your best to work on only your current assignment until your done with that one. nothing else.
-(if you do it at home) go into a silent room, like maybe yours, and close the door. take out anything that might distract you, like electronics.
-if you do this at home and use your computer/a computer and tend to go onto other websites for an hour instead of working, it might be best to ask someone to block those websites on your computer. thats the most major thing i can think of...
sorry if none of these helped, but i hope you end up passing this quarter!! :DLast two questions solve for X

Matteo spends a total of 38 min exercising. He walks for 6 min to warm up and then runs at a constant rate of 8 min per mile for the rest of the time. Matteo says that he ran 4.75 mi. Is he correct?
Answer:
No, he not correct because he only ran 4 mi
Step-by-step explanation:
If he walks for 6 min out of the 38 min, then he ran for 32 min.
d = rt 1 mi = 8r
r = 1/8 = 1 mi/8 min Since he ran 32 min we have
d = 1/8(32) = 4 mi.
No, he not correct because he only ran 4 mi

The table of values below represents an inverse variation relationship. what is the value of x when y= "3.25"?
X l Y
2 l 13
4 l 6.5
A. X=84.5
B. X=8
C. X=5.3
D. X=21.1
Using the constant of proportionality, the value of when y is 3.25 is 0.5 from the inverse variation.
What is inverse variation relationship?An rise in one variable causes a decrease in the other and vice versa in a mathematical relationship between two variables known as inverse variation, also known as inverse proportionality or inverse relationship. The following equation represents inverse variation:
y = k/x
In this equation, "y" and "x" stand in for the two variables, and "k" is the variational constant. Throughout the connection, the constant of variation has a set value that never changes.
Using the data given;
y = kx
Let's find the value of k;
k = constant of proportionality
13 = k(2)
k = 13/2
k = 6.5
Using the value of k;
3.25 = 6.5x
x = 3.25 / 6.5
x = 0.5
NB: The options given are incorrect and if you will follow through the steps, you will understand the options are incorrect.
