Answer: 80 degrees
Explanation: 145 + 134= 279
360-279= 80

Answer:

y = 81°

Step-by-step explanation:

180 - 145 = 35

180 - 134 = 46

180 - 35 - 46 = 99

180 - 99 = 81

75=(4x-25)

What is the value of x?

Answers

Answer:

x = 25

Step-by-step explanation:

75 = (4x - 25)

Since there are no numbers outside of the parentheses, we can remove them.

75 = 4x - 25

Now we can see that we can add 25 to both sides.

100 = 4x

Divide both sides by 4 to isolate x.

25 = x

Check by plugging in the value into the original equation.

75 = 4(25) - 25

75 = 100 - 25

75 = 75

Your answer is correct.

Hope this helps!

Three forces of sizes 15n,7n and 19n pulling at 120 degrees to each other are acting on a particle. What is the size of the resultant force and the direction

Answers

Answer:

10.58 N

Step-by-step explanation:

Let us find component of these forces in x and y direction.

The solution along with diagram can be found in attachment.

We have found resultant in X- direction = 6√3 N

resultant in Y- direction = 2 N

therefore net force resultant force = [tex]\sqrt{(6\sqrt3)^2+2^2}[/tex]

= 10.58 N

Find the value of x. Round to the nearest tenth.

Answers

Answer:

1) x = 20. 8

2) x = 42.3

3) x = 13.0

4) x = 42.1

Step-by-step explanation:

1) Use Sine

(Sine = [tex]\frac{opposite}{hypothenuse}[/tex]) Sine 53 = [tex]\frac{x}{26}[/tex]

(sine of 53 is 0.80) 0.80 = [tex]\frac{x}{26}[/tex]

(multiply 26 on both sides) 0.80 x 26 = [tex]\frac{x}{26}[/tex] x 26

(solve) 20.8 = x

2) Use Tan

(Tan = [tex]\frac{opposite}{adjacent}[/tex]) Tan 78 = [tex]\frac{x}{9}[/tex]

(tan of 78 is 4.70) 4.70 =  [tex]\frac{x}{9}[/tex]

(multiply 9 on both sides) 4.70 x 9 =  [tex]\frac{x}{9}[/tex] x 9

(solve) 42.3 = x

3) Use Cosine

(Cosine = [tex]\frac{adjacent} {hypothenuse}[/tex]) Cos 22 = [tex]\frac{14}{x}[/tex]

(cos of 22 is 0.93) 0.93 = [tex]\frac{14}{x}[/tex]

(multiply 14 on both sides) 0.93 x 14 = [tex]\frac{14}{x}[/tex] x 14

(solve) 13.02 = x

(round to the nearest tenth) 13.02 = 13.0

4) Use tan

(Tan = [tex]\frac{opposite}{adjacent}[/tex]) Tan 39 = [tex]\frac{52}{x}[/tex]

(tan of 39 is 0.809) 0.809 = [tex]\frac{52}{x}[/tex]

(multiply 52 on both sides) 0.809 x 52 = [tex]\frac{52}{x}[/tex] x 52

(solve) 42.068 = x

(round to the nearest tenth) 42.068 = 42.1

Answers

Answer:

No

Step-by-step explanation:

In order for it to be a function, every input (x values on the left) needs to be paired with only 1 output (y values on the right). Notice that 1 is paired with both 2 and 4.  This means it is not a function, but it is paired with two different values.


What is the value of s?
S=

Answers

Answer:

s = 1

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 5 , then

sum = 180° × 3 = 540°

sum the interior angles and equate to 540

39s + 129 + 79 + 145 + 148 = 540 , that is

39s + 501 = 540 ( subtract 501 from both sides )

39s = 39 ( divide both sides by 39 )

s = 1

Answer:

451.24

Step-by-step explanation:

first of all, you would subtract 53 from 623.45 then you would subtract 75 from the difference next you would subtract 7.29 from that difference lastly you would subtract 36.92 from that difference to find your answer

A man owns 3/4 of the share of a business and sells 1/3 of his shares for birr 10,000. What is the value of the business in birr?

Answers

Answer:

birr 40,000

Step-by-step explanation:

Given that :

Shares owns by a man in a business =  [tex]$\frac{3}{4}$[/tex]

Fraction of the shares sold by the man = [tex]$\frac{1}{3}$[/tex]

Amount for which the shares were sold = 10,000 birr

Let the value of the business of the ma be = x

Therefore, according to the question,

[tex]$\frac{1}{3} \text{ of } \left(\frac{3}{4}x\right) = 10000$[/tex]

[tex]$\Rightarrow \frac{1}{4}x = 10000$[/tex]

[tex]$\Rightarrow x = 4\times10000$[/tex]

       = 40,000

Therefore, the value of the share is birr 40,000
