Answer:
64 i think
Simple explanation:
find the missing angle of the triangle with two given angles:
add 36 and 84 to get 120
subtract 120 from 180 and you will get 60
subtract 60 from 90 to find one of the angles in the other triangle
so now you have that the other triangle has an angle of 86 and another angle of 30
add 86 and 30 to get 116
subtract 116 from 180 to get the "? angle"
you should get 64
Another possible explanation:
extend the line that contains the degrees 36 and 84
this will make a third, smaller triangle
this triangle has two measure that are easy to find and that is 96 and 54
when you add those together, you get 150
subtract 150 from 180 to get 30
30 degrees is the measure of the smaller angle at the 90 degrees symbol
now add 30 and 86 together to get 116
subtract that from 180 to get 64

Find the x-coordinate of the vertex, y-coordinate of the vertex, and the x-intercepts.
! pls help, I’ll mark as brainliest !
Answer:
X=-1
Y=-9
Step-by-step explanation:
x^2+2x-8
x^2+2x +1 =8+1
(x+1)-9
x coordinate of vertex x=-1, y coordinate of vertex y=-9 and x=2 and x=-4 are the x intercepts.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The given equation is y=x²+2x-8
then the x-coordinate of the vertex can be found using
x=-b/2a
x=-2/2=-1
x=-1 is the x coordinate of vertex.
substitute this value into f(x) for y coordinate
y=(-1)²+2(-1)-8
y=1-2-8=-9
y coordinate of vertex y=-9.
y intercept is -8.
To find the x intercepts x²+2x-8=0
x²+4x-2x-8=0
x(x+4)-2(x+4)=0
(x-2)(x+4)=0
x=2 and x=-4 are the x intercepts.
Hence, x coordinate of vertex x=-1, y coordinate of vertex y=-9 and x=2 and x=-4 are the x intercepts.

Find the measure of the exterior angle.
Answer:
1) 128°
2) 126°
3) 108°
Question one:The square in the corner means 90°. If you add the interior angles of any triangle together, you get 180. in this case, x is in exterior angle, so you subtract it from 180 to get the interior angle.
38 + 90 + (180-x) = 180
38 + 90 + 180 - x = 180
38 + 90 + 180 - 180 - x = 0
38 + 90 + 180 - 180 = x
128 = x
Question two:
again, adding all the interior angles makes 180°. use this to make the equation.
3x + (5x-6) + 90 = 180
3x + 5x - 6 = 90
8x = 96
x = 12.
x isn't the answer the question wants, however. if you look at the drawing, the angle that's supplementary to 5x-6 is the exterior angle. so,
180 - (5x-6) = the answer
180 - 5x + 6 = the answer
substitute x for 12
180 - 60 + 6 = the answer
126 = x
Question three
again, adding all the interior angles together makes 180°.
(a + 10) + 44 + (180-2a) = 180
a + 10 + 44 + 180 - 2a = 180
-a + 234 = 180
234 - 180 = a
54 = a
however, the question is looking for the exterior angle, not a. in this case, the exterior angle is 2a, so just multiply 54 by 2.
x = 108

Answer this for 15 points and Brainliest
Answer:
y=3x+18
Step-by-step explanation:
Since slope-intercept form is y=mx+b, we first need to find the slope.
m=y2-y1/x2-x1
m=0-(-9)/-6-(-9)
m=9/3=3
Next we need to find b, or the y-intercept
to do that we plug in numbers to what we already have.
y=3x+b
0=-18+b
b=18
Now we put it all together.
y=3x+18How do you solve this problem?

1. Which situation does NOT represent a functional relationship?
[A] Dave is a construction supervisor for several job sites. When Dave secures a contract for an additional job, he must hire 5 new construction workers to cover that Jobsite. The number of construction workers Dave oversees is related to the number of job sites under Dave's supervision.
[B] Betsy opened an account with $2,500 she had saved from a summer job. During the school year, she withdrew $200 each month from the account. The amount of money in Betsy's account is related to the number of months since Betsy opened the account.
[C] As a zoo veterinarian, Wanda is in charge of ordering vitamins for the spider monkeys. To be healthy, each monkey receives 3 vitamins. The number of vitamins that Wanda must order to have healthy spider monkeys is related to how many sider monkeys are kept at the zoo.
[D] Once a week, Rockwell participates in a soccer exercise. Based on Rockwell's performance, the soccer coach assigns two scores to Rockwell's evaluation form. How well Rockwell did on his performance as indicated by his scores is related to the number of weeks since Rockwell started practicing.

A. This is a functional relationship as the number of workers depend on the number of job sites.
y = 5xB. This is a functional relationship as the amount of money is dependent on the number of withdrawals
y = 2500 - 200xC. This is a functional relationship as the number of vitamins depend on the number of monkeys
y = 3xD. This is NOT a functional relationship as the output is a fixed value. The performance and scoring may repeat.

Can someone pls answer these questions for me I’m stuck
Answer:
a) The triangles are similar, and the ratio of the similar sides are both equal to 1:3. b) the scale factor from triangle abc to def is 3 because if you divide the longer corresponding side length from triangle def by the side of triangle abc, you will get 3. c) x is equal to 7.5 cm. Using the scale factor, you can just multiply 3 by 2.5.
Step-by-step explanation:
a) If you look at the two triangles, you can see that they look similar. Side AB looks similar to side DE, and the side lengths are 1 and 3. Therefore, the scale will be 1:3. b) If you divide the longer corresponding side length from triangle def by the side of triangle abc, you will get 3. c) x is equal to 7.5 cm because the scale factor is 3, which means you have to multiply the smaller side by 3.
