Answer:

x ≈ 12.22

Step-by-step explanation:

SOH CAH TOA(Tangent = opposite side/adjacent side)

tan (48°) = x/11

=> x = tan (48°) × 11

=> x ≈ 12.22

Answer:

C)

Step-by-step explanation:

Answer:

x= 14.8

Step-by-step explanation:

√12²+8²= 4√13

56.3= sin-¹(12/4√13)

tan56.3= 21.6/4√13

x+8= √21.6²+4√13²

x= 14.8

Answer:

N

Step-by-step explanation:

Since C is 48 you minus 6 from it since 6 is on the side so thus 48 - 6 = 42

Happy I can help

Answer:

48

Step-by-step explanation:

We are going to use trigonometry to solve for the wanted angle

Remember these are the trigonometric functions

( Remember SOH CAH TOA )

Sine = Opposite over Hypotenuse (SOH)

Cosine = Adjacent over Hypotenuse (CAH)

Tangent = Opposite over Adjacent (TOA)

For angle Ф

we are given its adjacent side length (6) and the hypotenuse (9)

Adjacent and hypotenuse corresponds with the trig function Cosine

So we will use cosine to solve for the missing angle

( let x = missing angle )

( remember cosine = adjacent over hypotenuse )

[tex]cosX=\frac{6}{9} \\\frac{6}{9} =.66\\cos(x)=.66[/tex]

now we want to get rid of the "cos" on the x

To do so we take the inverse of cos ( arc cos ^-!1 ) and apply it to each side

so...

[tex]arcos(cos(x))=x\\arccos(.66)=48.1[/tex]

we're left with x = 48.1

Answer:

Option B --> (8, -5)

Step-by-step explanation:

To find the midpoint, we use the equation-

[tex]\frac{x1 + x2}{2} , \frac{y1 + y2}{2}[/tex]

The coordinates given were (8, -2) (8, -8)

x1= 8,

x2 = 8

y1 = -2

y2= -8

Substituting these values in the equation:-

[tex]\frac{8+ 8}{2} , \frac{-2 + -8}{2}[/tex]

[tex]\frac{16}{2} , \frac{-10}{2}[/tex]

Coordinates of midpoint will be ---> (8, -5)

Answer:

[tex]x = \frac{5a-2} {7+5a}\\[/tex]

Step-by-step explanation:

Given the expressions

[tex]x = \frac{5}{9y+5}....1\\y = \frac{5}{5a-2} ...2[/tex]

Substitute 2 into 1

[tex]x = \frac{5}{9(\frac{5}{5a-2} )+5} \\x = \frac{5}{(\frac{45}{5a-2} )+5} \\x = \frac{5}{\frac{45+5(5a-2)}{5a-2} } \\x= \frac{5}{\frac{35+25a}{5a-2} }\\x = \frac{5(5a-2)} {35+25a}\\x = \frac{5(5a-2)} {5(7+5a})\\\\x = \frac{5a-2} {7+5a}\\[/tex]

Answer:

No triangle possible.

Step-by-step explanation:

3 + 6 < 10 so no triangle can be drawn with these lengths.

Answer:

hundredths

Step-by-step explanation:

the 4 is in the tenth place therfore the 6 is in the hundredth place because it is 46/100

Answer:

-15

Step-by-step explanation:

Answer:

On -15.

Step-by-step explanation:

So, the common difference seems to be 5.

Therefore, the point before -5 will be -10 and the point before -10 is -15.

Answer: W=15

Step-by-step explanation: The equation you set up is 2(L) + 2(W)=74

2(22) + 2W=74

44+2W=74

Subtract 44 from both sides

2W=30

Divide both sides by 2

W=15

Answer:

m<CAO = 56°

Step-by-step explanation:

Same-side interior angles are supplementary to each other, so take their sum and set them equal to 180 and solve for x:

2x + 3x + 40 = 180

5x + 40 = 180

5x = 140

x = 28

Plug x=28 into angle CAO:

CAO = 2(28) = 56°

Answer:

A rectangle is a parallelogram because parallelograms have to have exactly 2 pairs of parallel sides. A rectangle has 2 parallel sides, therefore it is considered a parallelogram.

Step-by-step explanation:

Answer:

decreasing because x is negative.

Answer:

The answer is 5.45%.

Step-by-step explanation:

29.99 - 24.49 = 5.5 which is the amount the price decreased.

Then, we divide the amount of decrease from the initial amount:

29.99 / 5.5 = 5.45

The answer is 5.45%

Answer:

3.5

Step-by-step explanation:

so this triangle is symmetrical by AA. so x would be symmetrical to 7, and 2.5 is symmetrical to 5.

[tex]\frac{x}{2.5}[/tex] = [tex]\frac{7}{5}[/tex]

x×5=5x

2.5×7=17.5

5x=17.5

x=17.5/5

x=3.5

Answer:

2.5

Step-by-step explanation:

Area of A is 50 cm ^2

length of A is 10

Area of B is 50/2 cm^2 or 25cm^2

area for all rectangles is length * width

so area of B divided by length of b is width of b

25/10 = 2.5

width of b is 2.5

Answer:

x = (-158)/87

Step-by-step explanation:

Solve for x:

38 x + 7 x + 7 x + 7 x + 7×4 (x + 7) = 38

Hint: | Multiply 7 and 4 together.

7×4 = 28:

38 x + 7 x + 7 x + 7 x + 28 (x + 7) = 38

Hint: | Group like terms in 38 x + 7 x + 7 x + 7 x + 28 (x + 7).

Grouping like terms, 38 x + 7 x + 7 x + 7 x + 28 (x + 7) = 28 (x + 7) + (38 x + 7 x + 7 x + 7 x):

28 (x + 7) + (38 x + 7 x + 7 x + 7 x) = 38

Hint: | Add like terms in 38 x + 7 x + 7 x + 7 x.

38 x + 7 x + 7 x + 7 x = 59 x:

28 (x + 7) + 59 x = 38

Hint: | Distribute 28 over x + 7.

28 (x + 7) = 28 x + 196:

28 x + 196 + 59 x = 38

Hint: | Add like terms in 59 x + 28 x + 196.

28 x + 59 x = 87 x:

87 x + 196 = 38

Hint: | Isolate terms with x to the left hand side.

Subtract 196 from both sides:

87 x + (196 - 196) = 38 - 196

Hint: | Look for the difference of two identical terms.

196 - 196 = 0:

87 x = 38 - 196

Hint: | Evaluate 38 - 196.

38 - 196 = -158:

87 x = -158

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 87 x = -158 by 87:

(87 x)/87 = (-158)/87

Hint: | Any nonzero number divided by itself is one.

87/87 = 1:

Answer: x = (-158)/87
