Answer: (0,4)
Explanation: What you're looking for is their point of intersection.
The point where the two lines intersect is the solution to the system.
In this case, the to lines intersect at the point (0,4).
So (0,4) is the solution to the system.
<span>It is important to know that the sum of the three angles inside a triangle add up to 180 degrees. So then we get the following by adding up all three provided angle measures:
3x + (2x + 20) + (4x - 20) = 180
Some algebraic manipulation follows:
3x + 2x + 20 + 4x - 20 = 180
9x = 180
x = 180/9 = 20
The value of x is 20 degrees.</span>
The Absolute Value of a number is "the magnitude of a real number without regard to its sign". So the Absoulute Value of 1/2 is |1/2|
