Answer:
24.54°Step-by-step explanation:
The three segments make a triangle with sides 6, 7 and 12 m.
We need to find the angle opposite to side 7 m.
Use the low of cosines to work out the angle x:
cos x = (6² + 12² - 7²)/(2*6*12)cos x = 0.9097x = arccos (0.9097)x = 24.54° (rounded)Can you guys help me find a flag that has at least one reflection and a translation in it? If not, then two flags that show these transformations.
This is very urgent and I need to get it done soon, whoever is willing to help me I'll mark you as brainliest. Thank you!
Answer:
The united nations flag the translation can be any of the blue triangles and the reflection if the flag itself as it is symmetrical
Step-by-step explanation:
The united nations flag the translation can be any of blue triangles and the reflection if the flag itself as it is symmetrical.
How does reflection across axis work?When a graph is reflected along an axis, say x axis, then that leads the graph to go just in opposite side of the axis as if we're seeing it in a mirror.
If we study it more, you will find that its symmetric, thus each point is equidistant from the axis of reflection as that of the image of that point.
If you're reflecting a point (x,y) along x axis, then its abscissa will stay same but ordinates will negate. Thus (x,y) turns to (x, -y)
Similarly, if you're reflecting a point (x,y) along y axis, the resultant image of the point will be (-x,y)
Therefore, The united nations flag the translation can be any of blue triangles and the reflection if the flag itself as it is symmetrical.

Step-by-step explanation:
I only see one phrase (correcting a typo) : "five more than a number".
that is expressed in math by using "n" for the variable "number " :
n + 5
or
5 + n

it costs $20 for 4 play tickets and $35 for 7 play tickets. is costs per ticket constant? why or why not?
Answer:
Yes.
Step-by-step explanation:
Most people are going to say 4x2=8 so 20x2=40, then do a huge math mess up and think they discounting $1.33 after the first 4. this is incorrect.
Seeing as $20 is 4 tickets we can safely say, each ticket is $5 each.
Basic mathematics, 5x7=35. Paying for 7 tickets at $5 each, that is the correct constant price.

Answer:
Yes they are. Explanation provided below.
Step-by-step explanation:
Two shapes are congruent when they are the same shape and size. Its obvious that both are rectangles and if we look at the grid, we can see that both rectangles are 2 by 4. Since they both have the same shape and size, they are in fact congruent.

The length and the width of a rectangle are (2x+5) cm and (2x-7) cm respectively. Given that the area of the rectangle is 14cm^2, find its length and width.
Answer:
Length=13.07 and Breadth=1.07
Step-by-step explanation:
Area=l*b
14=(2x+5)(2x-7)
14=4x^2-4x-35
4x^2-4x-49=0
Using quadratic formula, we have x=(1±5sqrt(2))/2 but as length can't be negative, so x=(1+5*sqrt(2))/2
Length=13.07 and Breadth=1.07

constant of variation?
Answer:
15
Brainliest, please!
Step-by-step explanation:
r = kp/(st)
