Answer:

Step-by-step explanation:
Let's start by taking a look at the blue line. The slope of any line that passes through two points is equal to the change in y-values over the change in x-values. We can see that the line passes through points (0, 1) and (1, 0). Assign these points to
and
(doesn't matter which you assign) and use the slope formula:

Let:

The slope is equal to:

Therefore, the slope of this line is -1. In slope-intercept form
,
represents slope, so one of the lines must have a term with
in it, which eliminates answer choices A and D.
For the second line, do the same thing. The red line clearly passes through (0, -3) and (3, -2). Therefore, let:

Using the slope formula:

Thus, the slope of the line is 1/3 and the other line must have a term with
in it, eliminating answer choice C and leaving the answer 
*You can find the exact equation of each line by using the slope formula as shown and plugging in any point the line passes through into 
<span>A polygon that is sometimes regular is a pentagon. A regular polygon is a polygon that has all sides equal and all interior angles are equal. Its sides and vertices are evenly spread around a central point, and a regular polygon is called convex where all the vertices point “outwards”.</span>
Point slope form (slope intercept form) is y = mx + b
so first move the -x over to the other side
2y = x + 10
Divide 2 to both sides
2y/2 = y
(x + 10)/2 = x/2 + 5
slope intercept form
y = x/2 + 5

Portion under square root sign:
= (b^2 - 4*a*c).
The base angles of an isosceles trapezoid are equal. Therefore:
20x + 9 = 14x + 15
6x = 6
x = 1
So, the base angles both equal 29 degrees.
In a trapezoid, the sum of the angles attached to the same leg always = 180 degrees.
Therefore, angle K and angle L equal 151 degrees.
