[tex]\begin{gathered} \qquad{\longrightarrow{\sf{Sum \: of \: all \: angles = {180}^{\circ}}}}\\\\ \qquad{\longrightarrow{\sf{{74}^{\circ} + {52}^{\circ} + 18u = {180}^{\circ}}}}\\\\\qquad{\longrightarrow{\sf{{126}^{\circ} + 18u = {180}^{\circ}}}}\\\\\qquad{\longrightarrow{\sf{18u = {180}^{\circ} - {126}^{\circ}}}}\\\\\qquad{\longrightarrow{\sf{18u = {54}^{\circ}}}}\\\\\qquad{\longrightarrow{\sf{u = \dfrac{54}{8}}}}\\\\\qquad{\longrightarrow{\sf{u = {3}^{\circ}}}}\\\\ \qquad\star{\underline{\boxed{\frak{\pink{u = {3}^{\circ}}}}}}\end{gathered}[/tex]

Hence, the value of u is 3⁰.

Answer:

C=83º

Step-by-step explanation:

It’s the same from the other side.

Answer: c=83 d=97

Step-by-step explanation: corrosponding angles are equal and angles on a straight line add to 180 so 180-83=97

90 - 53.45 = 36.55

36.55 / 7.31 = 5 pounds of coffee

Answer: The width is 9 units and the length is 20 units

Step-by-step explanation:

Perimeter is length + length + width + width, (P = 2l + 2w)

76 = 2(w+20) + 2w

76 = 2w + 40 + 2w

76 = 4w + 40

Subtract 40 on both sides

36 = 4w

Divide both sides by 4

9 = w

That means the length is 29 and the width is 9. To check out work, add 29+29+9+9 to get 76. Our answer is correct.

Answer:

  73.25 m

Step-by-step explanation:

In the right triangle formed by the pole, the ground, and the cable, the pole is the side opposite the angle of elevation, and the cable is the hypotenuse of the triangle. The relevant trig relation is ...

  Sin = Opposite/Hypotenuse

Solving for the Hypotenuse, we find ...

  Hypotenuse = Opposite/Sin

  cable length = (20 m)/sin(55°) ≈ 24.4155 m

The total length of the 3 cables is ...

  3 × (24.4155 m) ≈ 73.25 m

The total length of the cables is about 73.25 meters.

__

In the attached, we computed the length of a single cable for a pole 3 times as high. That will be the same length as the total we seek here.

Answer:

q = 5/18

Step-by-step explanation:

q + 5/9 = 5/6

Subtract 5/9 from each side

q + 5/9 - 5/9 = 5/6 - 5/9

q = 5/6 - 5/9

Get a common denominator of 18

q = 5/6 *3/3 - 5/9 *2/2

q = 15/18 - 10/18

q = 5/18

Answer:

Step-by-step explanation:

⭐ The question asks for the area of the restaurant which is in shape of circle.

⭐ The standard formula for calculating the area of circle is given by (A = πr²)

⭐ (π = 3.142 or 22/7), (r = 6miles) and we have to find the area (A) = ?

Given data:

Solution:

[tex]:\implies\tt{Area = \pi {r}^{2} }[/tex]

[tex]:\implies\tt{Area = 3.142 \times {6}^{2} }[/tex]

[tex]:\implies\tt{Area = 3.142 \times 6 \times 6}[/tex]

[tex]:\implies\tt{Area = 18.852 \times 6}[/tex]

[tex]:\implies\tt{Area = 113.112 {miles}^{2} }[/tex]

[tex]:\implies\tt{Area = 114 {miles}^{2} }[/tex]

Answer:

$0.18

Step-by-step explanation:

we need to set up two simultaneous equations

using variables, pencils = p and erasers = e

3 pencils and 2 erasers, the cost is $0.76

3p + 2e = $0.76

2 pencils and 4 erasers, the cost is $1.04.

2p + 4e = $1.04

we now have

3p + 2e = $0.76

2p + 4e = $1.04

to make the number of erasers the same, multiply the first equation by 2 to give 4e

2(3p + 2e = $0.76)

6p + 4e = $1.52

now we have the same number of erasers for both equations

6p + 4e = $1.52

2p + 4e = $1.04

subtract across: 6p - 2p = 4p, 4e - 4e = 0, $1.52 - $1.04 = $0.48

we are left with 4p = $0.48

divide both sides by 4

p = $0.12

1 pencil = $0.12

go back to the start of both equations and use one of them to find 1 eraser. I'll use 3p + 2e = $0.76

input $0.12 in p

3($0.12) + 2e = $0.76

$0.36 + 2e = $0.76

subtract $0.36 on both sides

2e = $0.76 - $0.36

2e = $0.40

divide 2 on both sides

e = $0.20

1 eraser = $0.20

How much more does 1 eraser cost than 1 pencil?

we now know 1 pencil = $0.12 and 1 eraser = $0.20

find the difference between them

$0.20 - $0.12 = $0.18

final answer= $0.18

29, 27, 25, 23, 21.......

term #1 = 31-2 = 29

term #2 = 31-4 = 27

term #3 = 31-6 = 25

term #4 = 31-8 = 23

term #5 = 31-10 = 21

...

tern #n = 31-2nStep-by-step explanation:

[B]

The answer to this question is very simple 120.

You can even do it systematically.

Take a=114, d = a2 - a1 = 116 - 114 =2

So now you get, a1= 114, d = 2

Now you want the 4th term so,

a4 = a + (n-1)d

a4 = 114 + 3 (2)

a4 = 114 +6 = 120
