write a paragraph proof for the following conjecture
Given m∠1 + m∠2 = m∠4
Prove: m∠3 + m∠1 + m∠2 = 180°

Answers

 m∠1 + m∠2 = m ∠4 , under the exterior angle property of a triangle which says that sum of the interior opposite angles of an exterior angle will be equal to the measure of the exterior angle .

To prove that m∠3 + m ∠1 +  m∠2 = 180° , let us use the angle sum property .

= Angle sum property = Sum of the three interior angles in a triangle will be equal to 180° .

= Since  ∠1 ,  ∠2 and  ∠3 are the interior angles of this triangle , their sum will be equal to 180° .

Hence proved that m∠1 +  m∠2 + m∠3 = 180°

∴ m∠1 +  m∠2 + m∠3 = 180° under the angle sum property of a triangle .

which is the correct value of c for x^2-14x+c=(x-7)^2

Answers

Answer:

c = 3.5 - x

Step-by-step explanati

x^2 - 14x + c = (x - 7)^2

x^2 - 14x + c = x^2 - 7^2

x^2 - 14x + c - x^2 = x^2 - 49 - x^2

-14x + c = 49

-14x / -14 + c = 49 / -14

x + c = 3.5

x - x + c = 3.5 - x

c = 3.5 - x

Answers

Slope is -13 and y-intercept is +1

Answer:

Hi there!

Your answer is:

slope: -13

y-int: 1

Step-by-step explanation:

The slope is the x coefficient, rise/run

In this case, its -13/1. Which means it has a slope of -13.

The y int is the constant term.

In this case, its 1. Which means it crosses the y axis at 1

to find the slope of the two points

Answers

Answer:

Slope is :-

[tex] \boxed{\bf \; m \; = - \cfrac{7}{5}} [/tex]

Step-by-step explanation:

Given two points :-

[tex] \sf \implies(-5,3) , (0,−4)[/tex]

To Find :-

The slope of Two points that is given.

Solution :-

[tex]\sf \implies(-5,3) , (0,−4)[/tex]

As we know that the formula of Slope is :-

[tex]\sf \implies \boxed{\sf Slope = \cfrac {y_2 - y_1}{x_2 - x_1}}[/tex]

Now, Put the values of x and y :-

Where,

[tex]{ \sf \: {y_2} = - 4}[/tex]

[tex] \sf \: x_2 = 0[/tex]

[tex] \sf \: y_1 = 3[/tex]

[tex] \sf \: x_1 = - 5[/tex]

Put the values on their respective place :-

[tex]\sf \implies \: Slope = \cfrac{ - 4 - 3}{0 - ( - 5)} [/tex]

Simplify this Fraction :-

Add -4 and -3 which is on the numerator as we know that "-" and "-" equals to "+":-

[tex]\sf \implies \: Slope = \cfrac{ - 7}{0 - ( - 5)} [/tex]

Now Add 0-(-5) on the denominator as we know that "-" and "-" equals to "+":-

[tex]\sf \implies \: Slope = \: \cfrac{ - 7}{ 5} [/tex]

Which can be rewritten as,

[tex]\sf \implies \: m = \: - \cfrac{7}{5} [/tex]

This fraction can't be cancelled. Hence, the slope of the two points is:-

[tex]\sf \implies \boxed{\sf m = \: - \cfrac{7}{5}} [/tex]

Note :- Slope can also be denoted as [tex] m [/tex].
