Given:
CDEF is a rhombus.
To find:
The value of x.
Solution:
We know that the diagonals of a rhombus are angle bisectors because they bisect each vertex angle.
[tex]5x+1=8x-20[/tex]
[tex]5x-8x=-1-20[/tex]
[tex]-3x=-21[/tex]
Divide both sides by -3.
[tex]x=\dfrac{-21}{-3}[/tex]
[tex]x=7[/tex]
Therefore, the value of x is 7.

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

5 16. Your checking account had a starting balance of $623.45. You make a withdraw at an ATM for $50 and are charged a $3 fee. You deposit a check from your mom for your birthday for $75 and then use your debit card for $7.29 at Dutch Bros. You write a check to T-Mobile for $36.92 for your monthly bill. What is your current balance?
Answers
Answer:
$601.24
Step-by-step explanation:
623.45 - 50 - 3 + 75 - 7.29 - 36.92 = 601.24
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
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

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

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

Answer:
12x + 3 + 7x - 13 = 180
Step-by-step explanation:
Q and R are Same Side Interior Angles
If you add any two same side interior angles for a trapezoid, they will equal 180 degrees.
Therefore, 12x + 3 + 7x - 13 = 180 degrees
Answer:
12x + 3 + 7x - 13 = 180
Step-by-step explanation:
The top and bottom sides of the trapezoid are parallel, but the sides are not. This means that the two angles that we are trying to find cannot be equal. In this case, this can only mean that both sides can be combined to complete a 180 degree angle. This can also be determined since they are supplementary angles, or angles that are adjacent to the opposite side of another base.
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!
