Answer:

x = 11

Step-by-step explanation:

Given

The attached triangle

Required

Find x

The theorem that applies to this question is the theorem of external angles. And it translates to:

11x +2 = 58 + 5x + 10

Collect Like Terms

11x -5x  = 58 + 10-2

11x -5x  = 66

6x = 66

Divide through by 6

\frac{6x}{6} = \frac{66}{6}

x = \frac{66}{6}

x = 11

The slope of the line below is -1. write the point-slope equation of the line using the coordinates of the labeled point.​
omeli [17]

Answer:

y+9=-1(x-4)

Step-by-step explanation:

Point Slope Form is:

y-y_1=m(x-x_1)

When:

'm' is the slope.

(x_1,y_1) is the coordinate.

We are given the slope of -1 and the coordinate of (4,-9).

So:

m=-1\\x_1=4\\y_1=-9

Using the information and replacing the values we get:

y+9=-1(x-4)

So, the line equation in point slope form should be: y+9=-1(x-4)

Please help ASAP work and answer please please

Answers:

8. 12x+3= 27

move 3 to the other side , sign changes from +3 to -3

12x+3-3=27-3

12x= 24

divide by 12 for both sides

12x/12=24/12

x= 2

9. 6(y-10)=42

mutiply the bracket by 6

(6)(y)(6)(-10)= 6y-60

6y-60= 42

move -60 to the other side, sign changes from -60 to +60

6y-60+60=42+60

6y=102

divide by 6

6y/6=102/6

y=17

10. 9x-2=4x+13

move +4x to the other side

9x-4x-2= 4x-4x+13

5x-2= 13

5x-2+2= 13+2

5x= 15

divide by 5 for both sides

5x/5= 15/5

x= 3

11. 4/3y+5/2y= 1

find the common denominator for both of the fractions which is 6.

Mutiply by 2 for 4/3y .

4(2)/3(2)y=8/6y

Mutiply by 3 for 5/2y

5(3)/2(3y)= 15/6y

8/6y+15/6y= 23/6y

23/6y= 1

Mutiply both sides by 6/23

23/6y(6/23)= 1 (6/23)

Cross out 6 and 6 , divide by 6 and then becomes 1.

Cross out 23 and 23, divide by 23 and then becomes 1.

1*1*y=y

y= 6/23

How do you solve for the area for a complex figure
Dmitriy789 [7]

Step-by-step explanation:

It varies depending on the structure of the figure your taling about. If it is a bunch of squares or rectangles, you get the perimeter of all sides and then you try to make the figure into smaller squares or rectangles. After that now find the perimeter of the new side (opposit side should tell you) and then find the area for all the rectangles and squares. After that step, you add all the areas together and...viola!!!! You get the area of the complex figure. If it is not a rectangle please comment with the object and I could help you.
