Which is the value of x in the triangle?1245°2O 12V2O6V3O 62O 43
Answers
C) 6√2
1) Examining this triangle, we can conclude this is a right triangle and state that we can find the missing side (the adjacent leg) to angle 45º using the following trigonometric ratio Cosine:
[tex]\cos (45)=\frac{adjacent\text{ leg}}{hypotenuse}[/tex]2) So we can plug into that the given values for those legs:
[tex]\begin{gathered} \cos \text{ (45)=}\frac{x}{12} \\ \frac{\sqrt[]{2}}{2}=\frac{x}{12} \\ \\ 2x=12\sqrt[]{2} \\ \frac{2x}{12}=\frac{12\sqrt[]{2}}{12} \\ \frac{x}{6}=\sqrt[]{2}\text{ x 6} \\ x=6\sqrt[]{2} \end{gathered}[/tex]Note that we cross multiplied those ratios, and divided them by 12. Finally, to get rid of the fraction x/6 we multiplied that by 6 on both sides.
3) Hence, the answer is 6√2

Rocco’s family is planning a reunion. Family members traveling from out of town have two options for airfare and hotels. As shown in the table, the cost of airfare for Option 2 is 0.75 times the cost of airfare for Option 1. For the same total cost, 12 family members can attend the reunion if they choose Option 2. Only 10 family members can attend if they choose Option 1. What is the cost of airfare for Option 1?
Answers
Option 1's airfare will set you back $2600.
The act of simplifying something such that it is simpler to carry out or understand, or the thing that is the product of this simplifying process: The group offers suggestions for streamlining business processes. This grossly oversimplifies what actually transpired. See.
We have been given that
For option 1
Airfare = $x
Hotel = $600
For option 2
Airfare = $0.75x
Hotel = $800
Only 10 family members can attend if they choose Option 1.
10x + $600 .........eq 1.
12 family members can attend the reunion if they choose Option 2.
12(0.75)x + $800
9x + $800 ........eq 2.
By using Eq (1) and Eq (2)
10x + $600 = 9x + $800
10x - 9x = $800 - $600
x = $200
Put the value of x in the eq (1)
Then we get 10x + $600
= 10 x 200 + $600
= 2000 + $600
= $2600
Hence , the cost of airfare for Option 1 is $2600.

Step 1
Draw the regular polygon to find out how many triangles are in it.

Step 2
Find the area of 1 triangle
[tex]\begin{gathered} \text{The angle at the center = 360}^o \\ \text{But since they are 5 triangles, each will have an angle of }\frac{360}{5}=72^o \end{gathered}[/tex]Since the two sides of each triangle are radius, then they share the same angle. Hence,

what is the measure of the third angle in right triangle if one angle measures 28 degrees?
Answers
In a right triangle, two of the sides meet at 90 degrees
This means that one of its angles is 90 degrees
we have also been told that another angle is 28 degrees
To get the third angle:
The Sum of angles in a triangle is 180 degrees
let the unknown side be represented by y
y + 28 + 90 = 180
y + 118 = 180
y = 180 - 118
y = 62
The third side is 62 degrees

x=15°
HOPE THIS HELPS
Answer:
x = 15
Step-by-step explanation:
If m and were parallel then
3x - 15 and 150 would be same- side interior angles and sum to 180° , so
3x - 15 + 150 = 180
3x + 135 = 180 ( subtract 135 from both sides )
3x = 45 ( divide both sides by 3 )
x = 15

Answers
Hello there. To solve this question, we'll have to remember some properties about finding slopes of lines and dilations.
Given that the rectangle KLMN is dilated by a scale factor of 3 with the origin being the center of the dilation, resulting in the image K'L'M'N', we need to find the slope of K'L' knowing the slope of KL is -3.
We start by drawing the situation:
Just as an example. The rectangle many not pass through the same points, but the center is at the origin, which means it intersects the x and y axis at symmetric points.
Now, remember a dilation is a transformation that stretches every side at once, or in other words, re-scales the entire figure by a factor.
Since this factor is 3, we would have something like the following:
