Answer:

x=45 degrees

Step-by-step explanation:

You can see based off of the markings on the 2 sides, that it is an isosceles triangle, so that means the 2 base angles are equal.

so 2x+90=180 degrees

so 2x=90 degrees

x=45

Answer:

x=45

Step-by-step explanation:

→a+b+c=180

→Angle a is given to be 90 degrees

→ Also the other to angles are the same length so the same angle

90+2x=180

Step 1: Subtract 90 from both sides.  

2x+90-90=180-90

2x=90

Step 3: Divide both sides by 2.

\frac{2x}{2} =\frac{90}{2}

x=45

<h2>Answer:</h2><h2>x=45</h2>

Refer to the equation 2 x − 6 y = 12. (a) Create a table of values for at least 4 points. Show your work. (b) Use the table of v
steposvetlana [31]
For easy calculation first transpose the equation into the y-intercept form then create your table and plot the graph.
 
       If   2x - 6y = 12
         then  -6y = 12 - 2x
                    6y = 2x - 12
                      y = [2 (x - 6)] /6
               ⇒    y = (x - 6) / 3

The table and graph are attached below.
