please please please help me​

Answer:

it's answer is 73°

Step-by-step explanation:

< DCB = 50°

< ACB = x

< CAB = 57°

< ABC = < DCB = 50° {Being alternate angles }

Now

x + 50° + 57° = 180° { being sum of angles of triangle }

x + 107° = 180°

x = 180° - 107°

Therefore x = 73°

Hope it will help :)❤

Answer:

D

Step-by-step explanation:

because the lines go in the order of the side than the angle and than the other side- and the lines also determine if the two sides are equal- i dont know if that makes sense

Step-by-step explanation:

70

Answer:

5 (2 x 7)

Step-by-step explanation:

( 5 x 2 ) 7 = 70

5 ( 2 x 7 ) also equals 70

10 x 7 could also work if your teacher isn't really picky about it.

Answer:

1.

d - adjacent

e - hypotenuse

f - opposite

2.

[tex]\sin \theta = \frac{12}{13},\\\\\cos \theta = \frac{5}{13},\\\\\tan \theta = \frac{12}{5},[/tex]

Step-by-step explanation:

1. The opposite side of an angle is the side that the angle faces or forms. The hypotenuse of a right triangle is always the longest side of the right triangle. The adjacent side is one side or leg next to the angle that is not the hypotenuse.

2. In right triangles only:

The sine of an angle is equal to its opposite side divided by the hypotenuse. (o/h)

The cosine of an angle is equal to its adjacent side divided by the hypotenuse. (a/h)

The tangent of an angle is equal to its opposite side divided by its adjacent side. (o/a)

Thus, we have:

[tex]\sin \theta = \frac{12}{13},\\\\\cos \theta = \frac{5}{13},\\\\\tan \theta = \frac{12}{5},[/tex]

Answer:

C

Step-by-step explanation:

To evaluate f(3) substitute x = 3 into f(x), that is

f(3) = [tex]\frac{1}{6}[/tex] × 3 = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex] → C

Answer:

minimum is $20

Step-by-step explanation:

.13 x 256.84 = 33.39

$33.39 is less than $20.00

Answer:

The answer would be C, or 3

Step-by-step explanation:

2x with a power of 2 to the power of 3 is 6x, with a power of five, plus y to the fower of 3.

Answer:

B

Step-by-step explanation:

2x+3 is a factor of f(x) means that f(x) = (2x+3)* something else

to find the root or the zero:

2x+3 = 0 so 2x = -3; x= -3/2 so B is correct

Answer:

The total area is 594cm.²

Step-by-step explanation:

The top and bottom each have a length of 36 cm.

Blue side:

36/3= 12cm. (36/3 for the length of one side of a blue square)

12*12= 144cm.² (area of one blue square)

144*3= 432cm.² (area of all the blue squares)

Orange side:

36/8= 4.5cm. (the length of one side of an orange square)

4.5*4.5= 20.25cm.² (the area of one orange square)

20.25*8= 162cm.² (the area of all the orange squares)

Total area:

432+162= 594 cm.²

I hope this makes more sense, have a great day :D

Step-by-step explanation:

Answer:

The shoreline places would get more rain

Step-by-step explanation:

Answer:

The inland would have warmer winters and colder summers, I believe.

Step-by-step explanation:

Water tends to heat up eaiser and cause humidity which makes everything feel hotter, so the summers would be super hot by the shore compared to farther inland.

Answer:

62 ft is the answer

Step-by-step explanation:

I did the test

Answer:

[tex]V_d=976.9ft[/tex]

Step-by-step explanation:

From the question we are told that:

Height of cylinder h_1=114 feet

Diameter d=1

Length of triangular prism [tex]l_2=34ft[/tex]

Width of triangular prism  [tex]w_2=34ft[/tex]

Height of triangular prism [tex]h_2=1 ft[/tex]

Generally the equation for Volume of the cylinder is mathematically given by

 [tex]V_c=\pir^2h[/tex]

Where

 [tex]r=d/2\\r=0.5[/tex]

Therefore

 [tex]V_c-=\pi*0.5*114[/tex]

 [tex]V_c=57\pi[/tex]

 [tex]V_c=179.1ft[/tex]

Generally the equation for Volume of a Rectangular prism is mathematically given by

 [tex]V_r=whl[/tex]

 [tex]V_r=34*34*1[/tex]

 [tex]V_r=1156feet[/tex]

Generally the equation for Volume difference  is mathematically given by

 [tex]V_d=V_r-V_c[/tex]

 [tex]V_d=1156-179.1[/tex]

 [tex]V_d=976.9ft[/tex]

Answer:

5x+4=-6

5x=-6-4

5x=-10

x=-10/5

x=-2

Step-by-step explanation:

Answer:

[tex] \sf \: x = - 2[/tex]

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ 5x + 4 = -6

Then the value of x will be,

→ 5x + 4 = -6

→ 5x + 4 - 4 = -6 - 4

→ 5x + 0 = -10

→ 5x = -10

→ 5x ÷ 5 = -10 ÷ 5

→ [ x = -2 ]

Hence, the value of x is -2.

Answer:

2 1/3 hours or 2 hrs, 20 min

Step-by-step explanation:

1 5/6 + 1/2

make mixed number into improper fraction and change 1/2 to 3/6

11/6 + 3/6 = 25/6

14/6 equals 2 2/6 which simplifies to be 2 1/3 or 2 hrs, 20 min

HOPE IT HELPS

(FROM CROSS)

Answer:

Step-by-step explanation:

you have to substitute x with -3, so where you see x in the equation you write a -3 and calculate

[tex]\frac{(x-2)(x+9)}{x(x+5)} = \frac{(-3-2)(-3+9)}{-3(-3+5)} = \frac{-5*6}{-3*2} =\frac{-5}{-1} =5[/tex]
