Answer:
x = 14
Step-by-step explanation:
Extend line AB so that it intersects ray CE at point G. Then angles BGC and BAD are "alternate interior angles", hence congruent.
The angle at B is exterior to triangle BCG, and is equal to the sum of the interior angles at C and G:
138 = (376 -23x) +(x^2 -8x)
Subtracting 138 and collecting terms we have ...
x^2 -31x +238 = 0
For your calculator, a=1, b=-31, c=238.

<em>Additional comment</em>
You will find that the solutions to this are x = {14, 17}. You will also find that angle BCE will have corresponding values of 54° and -15°. That is, the solution x=17 is "extraneous." It is a solution to the equation, but not to the problem.
For x=14, the marked angles are A = 84°, C = 54°.

Answer: the slope of the line is 2/1
Step-by-step explanation:
Find a point on the graph and the go up twice until you see another point on the graph. So go to the right once. So you have found the slope of the line which is 2/1.
Hope this helps ☝️☝☝
Supplementary angles must add up to 180 degrees.
3x-12=180
x=64 degrees
Answer:
The linear equation that represents each function is y=mx+b. While The m represent the slop so instead of writing you write the slope provided. Then multiply by the X + b which is your Y-intercept.
Here is an example,
The slope is 2/3 and the y intercept is 6, write a linear equation for this sequence.
y= (2/3). X +6
