Answer:
38.7
Step-by-step explanation:
[tex]\frac{sinA}{A}=\frac{sinB}{B}=\frac{sinC}{C}[/tex]
A, B and C are the sides of the triangle and sinA, sinB and sinC are the opposing angles
[tex]\frac{sin95}{43}=\frac{A}{27}[/tex]
[tex]A = sin^{-1} (\frac{27*sin95}{43} )=38.72018809[/tex]
I need help with my homework
Answer:
Step-by-step explanation:
1. b. Alt. Exterior angles
a. 7x + 8 = 6x + 18
c. x + 8 = 18
x = 10
d. 6(10) + 18 = 60 + 18 = 78
7(10) + 8 = 70 + 8 = 78
2. 15x + 10 + 12x + 8 = 180
same side angles
27x + 18 = 180
27x = 162
x = 6
15(6) + 10 = 90 + 10 = 100 degrees
12(6) + 8 = 72 + 8 = 80 degrees
3. 12x + 2 = 11x + 6
x + 2 = 6
x = 4
12(4) + 2 = 48 + 2 = 50 degrees
11(4) + 6 = 44 + 6 = 50 degrees
corresponding angles
I need help with this question
Answer:
286 Degrees
Step-by-step explanation:
A circle is 360 degrees, and from the question, we know that it is asking for ACB, so it would be 360 - 74, which is 286 degrees

Factor the following trinomial
[tex]9x^2-24x+16[/tex]
Please show work
=> 9x² - 24x + 16
Split the middle term(term with x) in such a manner so that the product of those parts is equal to the product of term with x² and constant. Here, those parts are 12 & 12 as 12*12 = 9*16.
=> 9x² - 24x + 16
=> 9x² - (12 + 12)x + 16
=> 9x² - 12x - 12x + 16
=> 3x(3x - 4) - 4(3x - 4)
=> (3x - 4)(3x - 4)
Method 2
=> 9x² - 24x + 16
=> (3x)² - 2(3x*4) + 4²
=> (3x - 4)²
=> (3x - 4)(3x - 4)
Method 3
In case if you can't find the factors of the middle term.
Say f(x) = 0, find the zeroes using quadratic formula. Zeroes of this eqⁿ are [-(-24) ± √24²-4(9)(16)] / 2(9) = 4/3 & 4/3
Therefore, f(x) = (x - 4/3)(x - 4/3) = (3x - 4)(3x - 4)/9
Ignore the numeric constant.
f(x) = (3x - 4)(3x - 4)
find x:x+x=20
please find x for me
Answer:
x = 10
Step-by-step explanation:
10 + 10 = 20
Good luck with your work!
Answer:
x = 10
Step-by-step explanation:
x + x = 20 can also be interpreted as 2x = 20. This makes it easier to solve for the variable.
To isolate x, do the inverse operation of multiplication. So, we have to divide both sides of the equation by 2.
[tex]\frac{2x}{2}[/tex] = [tex]\frac{20}{2}[/tex]
Simplify this equation for x = 10.
I hope this is helpful. Good luck ^^
On a standardized exam, the scores are normally distributed with a mean of 120 and
a standard deviation of 10. Find the z-score of a person who scored 115 on the exam
Answer: z= -0.5
Step-by-step explanation: mean m=120 and deviation s=10.
Z = (x-m)/s= (115-120)/10
Answer: z=−1.1
Step-by-step explanation:
z=\frac{x-\mu}{\sigma}
z=
σ
x−μ
z-score formula
z=\frac{104-115}{10}
z=
10
104−115
Plug in values
z=\frac{-11}{10}
z=

What are they coordinates
Answer:
let ABC be a right-angled triangle, where A is the right angle (left to right)
the original coordinates:
A (-8, 8)
B (-1, 8)
C (-8, 5)
by changing the coordinates from (x, y) to (-y, x)
A (-8, -8)
B (-8, -1)
C (-5, -8)

HELP!!!!! Question in picture!!!!
Answer:
x = 29
Step-by-step explanation:
We know that those two angles equal 180° so we combine those two equations and set them equal to 180°:
6x + 6 = 180°
Subtract 6 from both sides:
6x = 174°
Divide by 6:
x = 29

HELPL ME QUICK I STUCK
Answer:
red = 28 apples
green = 13 apples
equations:
r + g = 41
r = g + 15
Step-by-step explanation:
r = number of red
g = number of green
r = g + 15 (the number of red apples is 15 more than the number of green apples)
r + g = 41
Substitute the first equation into the second and solve for a numerical value of g
(g + 15) + g = 41
2g + 15 = 41
2g = 26
g = 13
Now solve for a numerical value of r
r = g + 15
r = 13 + 15
r = 28
checking the math:
r + g = 41
28 + 13 = 41
Please lmk if you have any questions.

joshua is planting a triangular garden he sketched his diagram measurements are 12m and 10m the questions asks to find the missing side PLZ THIS IS URGENT
Answer:
It's 16m
Step-by-step explanation:
Let's say the missing side is C, and since the triangle is right-angle triangle, you can use Pythagoras theorem. Which is
C squared is equal to A squared plus B squared
Like this: c^2 = a^2+b^2
Then
c^2= (10)^2 + (12)^2
c^2= 100 + 144
c^2= 244
c=
[tex] \sqrt{244} [/tex]
c = 15.6
