Answer:

Step-by-step explanation:

in order for it to be a triangle the angles have to add up to equal 180

5+75+100=180 so its not a

10+80+90=180 so its not b

20+60+100=180 so its not c

45+45+45=135 so its d because the angles dont add up to 180

50+50+80=180 so its not e

Answer:

Step-by-step explanation:

To be a triangle, you have to have 180 degrees. if you add up all of the sides, it should give you 180. If it doesn't, it isn't a triangle. I hope that helped! :)

Plz consider giving me brainliest answer as I am trying to reach a new level, thanks!

I don't know how to give brainliest tho.

A triangle has side lengths of 15 10 and 7 is it a right triangle

lions [1.4K]

Answer:

No, it is not a right triangle.

Step-by-step explanation:

Given:

The sides of the triangle = 15 10 and 7

To Find:

Whether the triangle is a right triangle = ?

Solution:

According to Pythagorean theorem , In an right triangle the the sum of the squares of the two smaller sides must equal to the square of the larger side

$a^2 +b^2 =c^2\\$

where

a and b are the smaller sides

c is the larger side

Now from the given data, lets assume

a = 10 and b =7 and c =15

Substituting in the above equation we get,

$(10)^2 +(7)^2 = (15)^2$

100 + 49 = 225

149 = 225

$149 \neq 225$

So, the given triangle is not a right triangle.

I need help with this question: Label: Coefficients, variables, terms, and constant. −2x2 + 9x − 3

iVinArrow [24]

Answer:

coefficients: {-2, +9, -3}

variables: {x}

terms: {-2x^2, 9x, -3}

constant: {-3}

Step-by-step explanation:

It is difficult to "label" here, so we'll list each, separated by commas.

Coefficients

Coefficients are the multiplicative factor of an expression. Depending on the expression of interest, it may consist of numbers, variables, or expressions. Here, we consider the expression of interest to be powers of x, so the coefficients are as listed. The last one (-3) is sometimes called a "constant coefficient." It multiplies x^0.

coefficients: {-2, +9, -3}

Variables

A variable is usually a letter, symbol, or sequence of letters and symbols, that stands for something else--usually an unknown quantity. Its meaning and value will depend on the context. Generic variables are usually taken from the end of the alphabet: x, y, z. Their capitalization, font, or face may give special meaning. For example bold-face capital letters may be used to represent vectors or matrices.

variables: {x}

Terms

A term is a product of coefficients and variables. Terms in a polynomial are separated by addition or subtraction symbols.

terms: {-2x^2, 9x, -3}

Constant

"Constant" usually refers to a term containing no variables. It generally refers to a value that doesn't change.

constant: {-3}

Write the equation of the line that passes through the given points (-6, 0) and (0, 3)

Tomtit [17]

Answer:

Step-by-step explanation:

Put (-6,0) and (0,3) into a table of values

form of the equation: mx+b

x -6 0

y 0 3

3/-6=-0.5 (m)

3=b (the value of y when x=0)

equation: y=0.5x+3
