Step-by-step explanation:
Absolute value of a number gives the positive quantity of the number.
For instance,
From this example, therefore we know that

In this question,
the line would be at x=15 and you would shade all to the left of the line and a point in that zone or on the line would work in the equation
Since AK = KD, then the triangle ABD is isosceles,
Then BD = AB. Denote AB by x and AK by y.
Then,
2x+4y=24 (the perimeter)
cos 60=y/x.
From the second equation we get
Plug in the first equation we get:
We deduce that
