Answer:
[tex]x = 9.9[/tex]
[tex]y= 7[/tex]
Step-by-step explanation:
Given
See attachment for triangle
Required
Find x and y
Considering [tex]\theta = 45[/tex]
From the attached triangle, length x is the hypotenuse and length y is the adjacent
Solving for x
[tex]Sin\theta = \frac{Opp}{Hyp}[/tex]
[tex]Sin\theta = \frac{7}{x}[/tex]
So, we have:
[tex]Sin45 = \frac{7}{x}[/tex]
[tex]x= \frac{7}{Sin45 }[/tex]
[tex]x = \frac{7}{0.7071}[/tex]
[tex]x = 9.9[/tex]
Solving for y
Considering [tex]\theta = 45[/tex]
[tex]Tin\theta = \frac{Opp}{Adj}[/tex]
So, we have:
[tex]Tin45= \frac{7}{y}[/tex]
[tex]y= \frac{7}{Tan45}[/tex]
[tex]y= \frac{7}{1}[/tex]
[tex]y= 7[/tex]
The value of x and y is 9.9 and 7.
Calculation of the value:Since theta is 45 degrees
So, we know that
Sin theta = opp/hyp
Sin theta = 7 /x
x = 7 / 0.7071
= 9.9
Now the value of Y should be
Tin theta = opp/hyp
y = 7 \tan 45
= 7 /1
= 7
Therefore, we can conclude that The value of x and y is 9.9 and 7.

Answer:
Step-by-step explanation:
the shape looks like a cube.. and maybe they say something about that outside of the picture, even but assuming that it is a cube, we know all the sides are the same.
we also know that the area of one side of the cube is 3 [tex]\frac{1}{4}[/tex]
so multiply that
W x L = area
3 [tex]\frac{1}{4}[/tex] * 3 [tex]\frac{1}{4}[/tex] = area
10 [tex]\frac{9}{16}[/tex] = area
10.5625 = area
those two answer above are the same .. just one is in fractions and one is in decimals
there are 6 sides on a cube, so multiply the above answer by 6
6* answer = 63.375
63 [tex]\frac{3}{8}[/tex] ( this is your answer)
both of those are also identical , but look different for the reasons I mentioned above
use which ever from seems better to you. :)

What are the coordinates if (-5,-6) is rotated by 180?
25 pts?
Answer:
(5,6)
Step-by-step explanation:
Initial Coordinate rotated 180° is just a sign change new coordinate
coordinate (x, y) rotated 180° is just a sign change (-x, -y)
if (-x, y) rotated 180° is just a sign change (x, -y)
if (x, -y) rotated 180° is just a sign change (-x, y)
if (-x, -y) rotated 180° is just a sign change (x, y)

The measure of an angle is 15 more than twice its supplement. Find the measure of the angle.
Please include an explanation if you could! :)
9514 1404 393
Answer:
125°
Step-by-step explanation:
Let x represent the angle in degrees. Its supplement is (180-x) degrees. The given relation is ...
x = 15 +2(180-x)
x = 375 -2x . . . . simplify
3x = 375 . . . . . . add 2x
x = 125 . . . . . . . divide by 3
The measure of the angle is 125°.

You have a coupon for 15%. How
much is your total cost if you leave
a 20% tip?
Answer:
$57.44
Step-by-step explanation:
1. subtract 15% from the bill with coupon:
$56.32 - ($56.32 x 0.15) = $47.87
2. add 20% to this new bill:
$47.87+(47.87 x 0.20) = $57.44

Use the graph to write a linear function that relates y to x.
A line graphed on a coordinate plane. The line passes through the points at ordered pair negative 2 commas 0 and ordered pair 0 comma negative 1.
Answer: y = -0.5*x - 1
Step-by-step explanation:
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
Here we know that we have a line that passes through the points (-2, 0) and (0, -1)
Then the slope for this line is:
a = (-1 -0)/(0 - (-2)) = -1/2 = -0.5
Then our line is something like:
y = -0.5*x + b
now we know that this line passes trough the point (0, -1), this means that when x = 0, y must be equal to -1
Then we can replace these values in the equation in order to find the value of b.
-1 = -0.5*0 + b
-1 = b
Then the equation is:
y = -0.5*x - 1

28.In the year 2006, the number of malaria patients admitted in the hospital of a state was 4375. Every year this number decreases by 8%. Find the number of patients in the year 2008?
Answer:number of patients in the year 2008 =3,703 Patients.
Step-by-step explanation:
Number of malaria patients admitted in the hospital of a state in 2006= 4375.
Number of malaria patients admitted in the hospital of a state in 2007 if there was Decrease by 8% in 2007
= 8% x 4375 =350
4375-350=4,025 patients
Number of malaria patients admitted in the hospital of a state in 2008 since there was Decrease by 8% in 2008
8% x 4,025.= 322
4,025-322=3,703 Patients.

x^2-6x=b, make x the subject
Answer:
x = 3 ±√(b + 9).
Step-by-step explanation:
We use Completing the Square:
x^2 - 6x = b
(x - 3)^2 - 9 = b
(x - 3)^2 = b + 9 Taking square roots of both sides:
x - 3 = ±√(b + 9)
x = 3 ±√(b + 9).

Question 15
Answer:
∠1 = 42°
∠2 = 48°
∠4 = 48°
∠3 = 21°
∠5 = 21°
Step-by-step explanation:
Given:
∠WZY = 138°
Find:
∠1
∠2
∠3
∠4
∠5
Computation:
WZ = ZY
So,
∠3 = ∠5
So,
∠3 + ∠5 + 138 = 180
2∠3 = 42
∠3 = 21°
∠5 = 21°
∠1 = 180 - 138
∠1 = 42°
∠W = ∠Y
∠X + ∠Y + ∠W = 180
42 + ∠Y + ∠W = 180
∠Y = 69
∠2 = 69 - 21
∠2 = 48°
∠4 = 48°
