two angles of a triange measure 50 and 20

what is the measure of the third angle of the triangle

Answers

Answer 1

Answer:

110

Step-by-step explanation:

In the triangle angle theorem the angles will all add up to equal 180.

180-20-50=110

Answer 2
The answer is 110 because the whole triangeln is 180

Does anyone know 3x=-12?​

Answers

3x = -12
3x/3 = -12/3
x = 4

Answer:

x=-4

Step-by-step explanation:

Divide 3 on both sides since you use the inverse to cancel out each other but you need to do it on both sides to make the equation balance.

3 divided by 3x is x

3 divided by -12 is -4

x=-4

Irfan incorrectly determined that the equation for the line on the graph is y = 0.5x +5. What is the correct equation for the line?

Answers

Answer:

y=-1x+0.5

Step-by-step explanation:

First calculate the slope of the line=y2-y1/x2-x1

Take any two points

1-3/2-1

-2/1

slope=-1

y=mx+c (equation for line)

Take any point and figure the value of c

1=-1x2+c

1/-2=c

c=0.5

y=-1x+0.5

[tex]x = 2 \: or \: \frac{ - 1}{6} [/tex]

Step-by-step explanation:

Lets open the brackets.

[tex]6 {x}^{2} - 12x + x - 2 = 0[/tex]

Now lets factorise it.

[tex] = > 6 {x}^{2} - 12x + x - 2 = 0[/tex]

[tex] = > 6x(x - 2) + 1(x - 2) = 0[/tex]

[tex] = > (x - 2)(6x + 1) = 0[/tex]

Here x will have two values.

1) [tex]x - 2 = 0[/tex]

[tex] = > x = 2[/tex]

2) [tex]6x + 1 = 0[/tex]

[tex] = > 6x = - 1[/tex]

[tex] = > x = \frac{ - 1}{6} [/tex]

The mean age of 12 women in an office is 26 years old.
The mean age of 4 men in an office is 29 years old.
What is the mean age (nearest year) of all the people in the office

Answers

Answer:

27

Step-by-step explanation:

Well, if the mean of 12 people is 26, you can imagine those 12 people are 26, so 26*12=312. Next, you do the same for the 4 men, so 29*4=116. Then you add those 2 numbers together, to get the total of 428. Divide that by the total amount of people in the office which is 428/16=26.75. Rounding up (because the decimal starts with a number above 5) you get that the average age is 27.

Draw two intersecting line segment AB and CD intersecting at O. Measure the size of each pair of vertically opposite angles. Verify that each pair of vertically opposite angles are equal.

Answers

Answer:

Angles vertically opposite to each other are equal.

Step-by-step explanation:

There are two lines AB and CD intersecting at point O making angles 1 ,2,3 and 4.

The angles 1 and3  , angles 2 and 4 are vertically opposite angles.

Now consider the line AB

<1 + <2= 180 degrees--------- eq A

Now consider the line CD

<2+ <3= 180 degrees-----------eq B

As both equations are equal

< 1+ <2= <2+ <3 = 180 degrees

or

< 1+ <2= <2+ <3     or

< 1=  <3                           subtracting <2 from both sides

Now consider the line BA

<3+ <4= 180 degrees--------- eq C

Now consider the line DC

<4+ <1= 180 degrees-----------eq D

As both equations are equal

< 3+ <4= <4+ <1 = 180 degrees

or

< 3+ <4= <4+ <1    

or

< 3=  <1                           subtracting <4 from both sides

This holds true for all vertically opposite angles that they are equal.

These can be measured with a protractor.

This can also be proved that if we add angles 1,2,3 and 4 we will get 360

and if we subtract  angles 1 & 2 from 360 we will get 180 degrees which angles 3&4 make together.

<1+<2+<3+<4= 360 degrees

But <1 +<2= 180  

360 - [ <1+<2] = 180 degrees

<3 +<4= 180  

<1 +<2= <3 +<4= 180

The equation tan(55 degree) equals StartFraction 15 Over b EndFraction can be used to find the length of Line segment A C.

Answers

Given:

The equation is

[tex]\tan(55^\circ)=\dfrac{15}{b}[/tex]

To find:

The length of the line segment AC.

Solution:

We have,

[tex]\tan(55^\circ)=\dfrac{15}{b}[/tex]

[tex]1.428148=\dfrac{15}{b}[/tex]

Multiply both sides by b.

[tex]1.428148b=15[/tex]

Divide both sides by 1.428148.

[tex]b=\dfrac{15}{1.428148}[/tex]

[tex]b=10.50311[/tex]

[tex]b\approx 10.503[/tex]

In a triangle ABC, the line of line segment AC is b. So,

[tex]AC\approx 10.503[/tex]

Therefore, the length of the line segment AC is 10.503 units.

Tell whether the ordered pair is a solution of the system of linear equations.
y = -5x + 2
y=x-4
(2-8)

Answers

the ordered pair is not a solution of the system of linear equations.

if it was a solution of the system, when you plug in 2 for x to solve for y, -8 should be the answer for both equations but it’s not.

for y = -5x + 2
y = -5(2) + 2 = -10 + 2 = -8

for y = x - 4
y = 2 - 4 = -2

(2, -8) isn’t a solution

In which quadrant does the point (15,-7) lie?

Answers

Answer:

Quadrant 4

Step-by-step explanation:

Quadrant 1: Positive x and Positive y

Quadrant 2: Negative x and Positive y

Quadrant 3: Negative x and Negative y

Quadrant 4: Positive x and Negative y

For point (15, -7), we have a Positive x and a Negative y so it belongs in Quadrant 4.

The quadrant the given point (15,-7) lie is fourth  quadrant.

The first quadrant in Cartesian coordinate is given as;

= (x, y)

The second quadrant in Cartesian coordinate is given as;

= (-x, y)

The third quadrant in Cartesian coordinate is given as;

= (-x, -y)

The fourth  quadrant in Cartesian coordinate is given as;

=(x, -y)

(15,-7) corresponds to (x, -y)

Thus, the quadrant the given point lie is fourth  quadrant.

Answer:

a. yes

b. no

c. no

d. no

e. yes

Step-by-step explanation:

Here, we want to answer yes or no for each of the numbers

a) Yes

If we compare with the general form

y = mx + b

m

is slope and b is y-intercept

so, 2 is slope and 3 is y intercept; so 3 in y-intercept is (0,3)

b. No

This is the point-slope form we are trying to

get

Evaluating this, we have that

y-3 = 2x - 6

y = 2x-6 + 3

y = 2x-3

c) NO

Just insert the values and check here

-1 = 2(5) + 3

it does not work

d) No

Substitute

-4 = 2(-5) + 3

e) Yes

This is the point-slope form

y + 3 = 2x + 6

y = 2x + 6-3 = 2x + 3

Find the slope and y intercept
