15x + 90 + 8x-2 = 180
23x + 88 = 180
23x = 92
x = 4
Answer:
x = 4
Step-by-step explanation:
The easiest way to do this is to look at the vertical angles. (15x)º has its own vertical angle, and the part with (8x-2)º and 90º does as well.
Also, every angle will add up to 360º, which is a crucial part of the equation
Do 15x + 15x + 90 + 90 + 8x - 2 + 8x - 2 = 360
This can be simplified into this once you combine like terms:
46x + 176 = 360
Subtract 176 from 360, which will give you:
46x = 184
Divide by 46 on both sides, resulting in:
x = 4
To check the answer, plug in 4 for x:
15(4) + 15(4) + 90 + 90 + 8(4) - 2 + 8(4) - 2 = 360
60 + 60 + 90 + 90 + 32 - 2 + 32 - 2 = 360
120 + 180 + 60 = 360
360 = 360, x is 4
Hope this made sense!

Answers
good luck and pls mark brainliest if correct
Answer:
The tax on her purchase is $63.35
Step-by-step explanation:
$33.62 + $23.95 + $13.78 = $71.35
$17.35 - 7.5 = $63.85
$63.85 - 0.5 = $63.35

The science club has m members. The club bought 24 bumper stickers to split among its members. Write an expression that shows how many bumper stickers each member will get.
Answers
Answer: 24/m
Step-by-step explanation:
There are m members in the science club.
24 bumper stickers were purchased to be split amongst these m members.
The number of stickers that each member will get is:
= Number of stickers / Number of members
Number of stickers = 24
Number of members = m
The expression is therefore:
= 24/m

Amanda is hosting a school play at Midtown High School. To buy a ticket, she charges
$11 per child and $13 per adult. If there are a total of 214 tickets sold and she earns a
revenue of $2,592, how many adults and how many children attended the play?
Answers
Answer:
119 adults, 95 kids
Step-by-step explanation:
11x+13y=2592
X+y=214
11x + 13(214-x) = 2592
11x + 2782 -13x = 2592
-2x = -190
X = 95
95 + y = 214
Y= 119
I do not understand it answer with explanation too please
Answers
Answer: x = 10
Step-by-step explanation:
The sum of all interior angles in a polygon add up to 360°
Meaning to find X we grab those numbers/variables and make them equal to 360°. This will give us an equation.
106 + 94 + 135 + x + ( x + 5 ) = 360
335 + x + x + 5 = 360
340 + 2x = 360
subtract 340 from both sides
2x = 20
Divide by 2
x = 10
Now solve the angle equations to find their angle.
( 10 + 5 ) = 15
x = 10
Now to check if it's right add them together
106 + 94 + 15 + 10 + 135 = 360 ( ITS CORRECT )

find the value of x when hypotenuse is 20 and degree is 35
Answers
Answer:
There are two solutions, depending on where x is. Since you did not attach a picture, I did both. Choose the one that matches your picture/question.
If x is on the opposite side (solution 1 photo), then, x = sin(35)*20 equals about 11.47
If x is on the adjacent side (solution 2 photo), then x = cos(35)*20 equals about 16.38
Step-by-step explanation:
I love trigonometry, once you start practicing it, it becomes second nature. We're given that the hypotenuse is 20 and an angle is 35 degrees. I have attached a picture of the drawing (GIVEN). We know that the hypotenuse is the longest side of the triangle and directly across from the right angle. Then, we can put the 35 degrees in any other spot, if you are not given a picture. Next, I like to label all the sides, o for opposite, a for adjacent, and h for hypotentuse.
After labeling the drawing, you should be able to set up an equation, using sine (o/a), cosine (a/h), or tangent (o/a) depending on the given. To help you remember this, you can use the saying SOH CAH TOA, which is sin = opposite/hypotenuse, cosine = adjacent/hypotenuse, and tangent = opposite/ajacent. In this problem, we are going to use one that has the hypontenuse, so you can automatically get rid of the tangent. You did not include of photo, so I am going to solve for it both ways. I will edit it, if you attach of photo later.
SOLUTION 1:
sin(35) = x/20
x = sin(35)*20
x equals about 11.47
OR
SOLUTION 2:
cos(35) = x/20
x = cos(35)*20
x equals about 16.38
Once again, this depends on where x is on the triangle. And since you did not include a picture, I am unable to fully tell you.
Hopefully this still helped you, good luck!

The Pythagorean theorem is a formula to solve for hypotenuse the formula is a squared plus b squared equals c squared. The Pythagorean theorem was made by someone for math which is four triangles that A in the equation is for the side of the right triangle B is for the other side and C is the hypotenuse. the photographer in theorem states that the sum of the squared sides of a right triangle equals the length of the hypotenuse. It is a fundamental relationship between the three sides of a right triangle; you must use two sides in order to find the hypotenuse. many ways to make a formula for the Pythagorean theorem but the most popular one is a squared plus b squared equals c squared. there's a book and it's called the Pythagorean proposition it contains over 300 formulas for the Pythagorean theorem. a man who went by Pythagoras had found the Pythagorean theorem in the school of mathematics and Cortana he was a Greek Seaport in southern Italy he was going to get too many contributions to mathematics although some of them may have actually been the work of his students that he had taught. Pythagorean theorem is the most famous mathematical contribution in history. It was created in 1900 BC. the reason why it was created that the Egyptians wanted a perfect 90° angle to build the pyramids which were actually two right triangles whose hypotenuse form the edges of the pyramid. there is a rumor that the Chinese had also developed the Pythagoras Theorem using the areas of the sides long before Pythagoras himself.

Answer:
c) 30
Step-by-step explanation:
since the lines are parallel, 75° = 2x + 15°
this is because when two parallels lines are intersected by the same line, all respective angles are equal. Also, opposite angles on a line are equal too.
So now that u have 75 = 2x + 15, just solve for x by simplifying:
75 = 2x + 15
60 = 2x
30 = x
so the answer is c) 30

Parallelogram JKLM is shown.
Parallelogram JKLM is divided into 4 triangles by K M and J L which intersect at point R. Angle L M K is 72 degrees, angle K J L is 56 degrees, and angle J M K is 27 degrees.
If KR = x + 7, KM = 3x − 5, and JL = 4x − 10, what are the values of x and JR?
Answers
The measure of x and JR are 19 and 33 respectively
From the given parallelogram,
KM = 2KR
Given the following
KM = 3x - 5KR = x + 7Hence;
3x - 5 = 2(x+7)
3x - 5 = 2x + 14
3x - 2x = 14 + 5
x = 19
Similarly, JL = 2JR
JR = JL/2
JR = 4x-10/2
JR = 4(19)-10/2
JR = 66/2
JR = 33
Hence the measure of x and JR are 19 and 33 respectively
