This is actually quite simple. You just have to remember that a triangles angle measures must equal up to 180. Also, you need to recognize which angles are supplementary angles (angles whose measure must add up to 180) That being said, 126 and A are supplementary angles. So are C and 41, and E and 38. To find out A, simply subtract 126 from 180 to get 54. Then, to get C, subtract 41 from 180 to get 139. Since you know A and C, you can figure out B, which is 85. Then, to find E, subtract 138 from 180. That equals 42. Now, simply add up 41 and 42, and shbtract it from 180. That gives you 97, which is D. I hope this helps! :)

Write an equation in slope intercept form of the line containing the points (-2,5) and (9,-6)

otez555 [7]

(-2,5)(9,-6)
slope(m) = (-6-5) / (9 - (-2) = -11/11 = -1

y = mx + b
slope(m) = -1
(-2,5)...x = -2 and y = 5
now we sub and solve for b, the y int
5 = -1(-2) + b
5 = 2 + b
5 - 2 = b
3 = b

so ur equation in slope intercept form is : y = -x + 3

NO LINK SPAM OR REPORT: Tell whether x and y show direct variation. Explain your reasoning. If so, find k.

sergeinik [125]

Answer:

2. yes; the equation can be written as y = kx; k = 1

Step-by-step explanation:

x-y = 0

That means x and y have to be the same value.

If you multiply a number by 1, you get the same thing.

If you multiply x by one, you get y (the same value).

Hope this helps!

A manager finds a moderate negative correlation between the number of computer sales and the number of microwave sales in his st

BabaBlast [244]

Answer:

C) The correlation is most likely a coincidence.

Step-by-step explanation:

By general comprehension of the population and their buying habits, I don't think we can really establish a relation between the sales of computers and the microwaves in a general manner. If the store is located near a university residence and it's September, there might be a link to be done, but in general, no.

It's not like some enters a store and says "Ok, will I buy a microwave or a computer today?". Those are two totally different products, with different clienteles and different needs.

Since SSS guarantees that two triangles are congruent, one might think that SSSS guarantees that two quadrilaterals are congruen

timurjin [86]

Answer:

Below.

Step-by-step explanation:

When you graph this you'll see that it is a rhombus, which has 4 equal sides and the 4 angles are not 90 degrees.

You could draw a square on the coordinate plane using A(0.0). B (0,3), C(3,3) and D(3,0). The sides of the square are all equal to the sides of the rhombus but the 2 quadrilaterals are not congruent because the angles have different values,

A wire that is 22 feet long connects the top of a pole to the ground. The wire is attached to the ground at a point that is 10 f

krok68 [10]

✰ Concept Used :-

⠀

In this question, we can clearly observer that the diagram shows a right angled triangle. And, we have been provided with the value of base, and the value of hypotenuse, using the pythagoras theorem, now we can easily find out the value of the perpendicular i.e. the value of the side h. According to the pythagoras theorem, square of hypotenuse is equal to the sum of square of perpendicular and square of side respectively. Therefore, square of side is equal to the difference of square of hypotenuse and square of perpendicular.

⠀

✰ Given Information :-

⠀

Hypotenuse = 22 ft.
Base = 10 ft.

⠀

✰ To Find :-

⠀

The value of side or the perpendicular

⠀

✰ Formula Used :-

⠀

$\star \: \underline{ \boxed{ \purple { \sf {Side}^{2} = {Hypotenuse}^{2} - {Base}^{2} }}} \: \star$

⠀

✰ Solution :-

⠀

$\sf \longrightarrow {Side}^{2} = {(22 \: ft)}^{2} - {(10 \: ft)}^{2} \: \: \: \\ \\ \\ \sf \longrightarrow {Side}^{2} = {484 \: ft}^{2} - {100 \: ft}^{2} \: \: \: \: \: \: \\ \\ \\ \sf \longrightarrow {Side}^{2} = {384 \: ft}^{2} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \\ \sf \longrightarrow {Side}^{} = \sqrt{ {384 \: ft}^{2} } \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \\ \sf \longrightarrow {Side}^{} = \underline{ \boxed{ \frak{ \green{19.60 \: ft}}}} \: \star \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\$

Thus, option B. 19.60 ft. is the correct option.

⠀

$\underline{\rule{230pt}{2pt}} \\ \\$
