we know that

The sum of the internal angles of a triangle must be equal to 180 degrees

see the attached figure with letters to better understand the problem

m∠B+(6x+1)=180°-----> by supplementary angles

m∠B=179-6x

m∠A=2x+10

m∠C=79

m∠A+m∠B+m∠C=180

Substitute

(2x+10)+(179-6x)+79=180\\ -4x+268=180\\ 4x=268-180\\ 4x=88\\ x=22\ degrees

therefore

the answer is

the value of x is equal to 22\ degrees

Answer:

<u>Part A</u>

 A_{t}=22(12+w)

Applying Distributive property: A_{t}=264+22w

<u>Part B</u>

A_{t}=660\ ft^2

Step-by-step explanation:

<em><u> Attached is the model that belongs to this exercise (The model was missing)</u></em>

The formula for calculate the area of a rectangle is:

A=lw

Where "l" is the lenght and "w" is the width.

<u>Part A</u>

Notice that the dimensions of the new bathroom are:

l=22\ ft\\w=12\ ft

We do not know the width of the new bathroom, but we know that both rooms will have the same length. Knowing this, we can write an expression for the total area of both rooms by using the Distributive Property:

A_{t}=22(12+w)

Applying Distributive property:

 A_{t}=264+22w

<u>Part B</u>

If the width of the bedroom is 18 feet, you need to substitute this value into the expression A_{t}=264+22w in order to find the total square footage of the two rooms:

A_{t}=264+22w\\\\A_{t}=660\ ft^2

Anyone know the area?
Elina [12.6K]
Answer:  The area of the triangle is:  " 8.5 cm² " ; 

                                         or, write as:  " 8\frac{1}{2} cm² " .
_______________________________________________________
Explanation:
_________________________________________________________
The formula {"equation"} for the area of a triangle is:

A = (\frac{1}{2}) * b * h ;
   
in which:  A = area; 
                 b = base;
                 h = [perpendicular] height;
___________________________________
{also, can be written as:  " A = (b * h) / 2 " .}.
______________________________________
Solve for the area, "A" ; by plugging in the known values shown in the figure (image attached):
______________________________________
                             base, "b" = 13 cm ;
[perpendicular] height, "h" =  5 cm ;
______________________________________
A = (b * h) / 2 ;

   = (13 cm * 5 cm) / 2 ; 

   = [ (13 * 5) cm²] / 2 ; 

    = 65 cm² / 2 ;

A  = " 8.5 cm² " ; or, write as:  " 8\frac{1}{2} cm² " .
_________________________________________________________
Answer:  " 8.5 cm² " ; or, write as:  " 8\frac{1}{2} cm² " .
