Which pair of angles has congruent values for the sin x° and the cos y°?
35°; 55°
35°; 70°
35°; 145°
35°; 35°
Answer: the correct answer is A. 35, 55
Step-by-step explanation: got it right on my exam today
35 degrees and 55 degrees are the pairs of angle have congruent value for sinx and cosx.
What is congruent angle?Congruent angles are the angles that have equal measures.
According to the given question
We have different angles for [tex]sinx[/tex] and [tex]cosy[/tex].
And we have to find "the pairs of angles which has congruent values for sinx and cosy.
Therefore,
35 degree and 55 degree
sin(35) = [tex]sin(\frac{7\pi }{36})[/tex] =0.57
cos(35) = [tex]cos(\frac{11\pi }{36})[/tex] = 0.57
⇒ 35 degrees and 55 degrees are the pair of angles has congruent values for sinx and cosy.
35 degrees and 70 degrees
sin(35) =[tex]sin(\frac{7\pi }{36} ) =0.57[/tex]
cos(70) =[tex]cos(\frac{7\pi }{18} )[/tex] = 0.34
⇒35 degrees and 70 degrees are the pair of angles have not congruent values for sinx and cosy.
35 degrees and 145 degrees.
sin(35)=[tex]sin(\frac{7\pi }{36} )= 0.57[/tex]
cos(145) = [tex]cos(\frac{29\pi }{36} )= -0.8[/tex]
⇒ 35 degrees and 145 degrees are the pair of angles have not congruent values for the sinx and cox.
35 degrees and 55 degrees
sin(35) =[tex]sin(\frac{7\pi }{36} )[/tex]= 0.57
cos(35) = [tex]\frac{x}{y} =\frac{7\pi }{36} = 0.8[/tex]
⇒ 35 degrees and 55 degrees are the pairs of angles have not congruent values for sinx and cosx.
Hence, 35 degrees and 55 degrees are the pairs of angle have congruent value for sinx and cosx.

Ms Hart had 40 dollars to spend on costume boxes for the musical. If she bought 12 boxes and received 4 dollars in change, how much was each box?
Answer:each box cost =$3
Step-by-step explanation:
Amount of money Ms Hart has to spent on costume boxes=$40
Amount gotten as change after purchase=$4
Amount actually used up buying costume boxes =$40-$4=36
Since she bought 12 boxes , each box cost =$36/ 12=$3

Marshall is comparing different companies that rent sound systems The total cost, y , for each company includes a used rental fee plus an additional fee based on the number of hours, x , the sound system is rented. Which company had the lowest additional fee per hour for renting a sound system?
Answer:
Company B
Step-by-step explanation:
Given
See attachment for graph
Required
Company with the least additional fee
This means the y-intercept and it represents the flat fee
To get the y-intercept, we simply write out the point where [tex]x= 0[/tex]
From the graph of A, we have:
[tex](x,y) = (0,70)[/tex]
Additional Charges = 70
From the table of B, we have:
[tex](x,y) = (0,50)[/tex]
Additional Charges = 50
From the equation of C, we have:
[tex]y=10x+ 90[/tex]
[tex]y(0) = 10 * 0 + 90[/tex]
[tex]y(0) =0 + 90[/tex]
[tex]y(0) =90[/tex]
Additional Charges = 90
By comparison. company B has the least additional fee because: [tex]50 < 70 < 90[/tex]
What is the sum of the interior angles in this shape?
Answer:
720° :)
Step-by-step explanation:
You can find the total interior angle for any shape using the following (n being the number of sides):
S = ( n - 2 ) × 180 °
S = (6-2) * 180
S = 720

Answer: yes they are
Step-by-step explanation: the way you know is because the angles on each shape are the same and the lines on the shapes are the same length. If one shape is bigger than another or if one has a different shape than the other, they are not congruent. I hope that helped you!
ill give brainliest to the correct answer
Answer:
7 x 4 = 28
28 x 1/2(dividing by 2) = 14, 14 x 2(two triangles) = 28
4 x 5 = 20(area of square in the middle)
5 x 8 = 40(area of square on one side), 40 x 2 = 80(area of squares on both sides)
Now lets add the given areas:
28 + 20 + 80 = 128 square is your answer.

Tom can paint a fence in 6 hours. Huck can paint a fence in 5 hours. If Tom takes a 30 minute break, how long will it take them to paint the fence together?
Answer:
4 1/11 hours
Step-by-step explanation:
Tom can paint 1/6 of the fence in an hour
Huck can paint 1/5 of the fence in an hour
Tom takes a half-hour break; we can create this equation:
1/6x - 1/2 + 1/5x = 1
use a denominator of 30:
5x/30 - 15/30 + 6x/30 = 30/30
11x/30 = 45/30
multiply each side by 30/11 to get:
x = 45/11 or 4 1/11

m∡ABC = 135°
Step-by-step explanation:
∡ABE ≅ ∡CBD therefore we can create the following equation:
3x + 27 = 45
3x = 18
x = 6
∡CBD and ∡ABC are supplementary so 180 - ∡CBD = m∡ABC
180 - 45 = m∡ABC
m∡ABC = 135°

HEY BESTIES, HOW DOES AN OUTLIER AFFECT THE DISTRIBUTION OF A DATA SET?
Basically, an outlier is a point on a graph that doesn't really fit the pattern.
An outlier can throw off a mean, if the outlier is larger than the other points, it can make the mean much higher than it should be. Vice versa, if it is smaller, the mean is much lower.

= 30
∵ The maximum number of different outfits would be 30.

Help I suck at math
Answer:
A
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
We can use this formula to find the equation of the line
(y-y1)/(y2-y1) = (x-x1)/(x2-x1)
(y - 11)/(23-11) = (x-1)/(3-1)
(y-11)/12 = (x-1)/2
y-11 = 6x-6
y = 6x + 5
the rate of change is the slope of the line, while the constant (5) is the y intercept
