Okay, so to start, the bottom line equals 180°, so the two angles combined must equal that, right?
Next, come up with the equation:
After that, you can combine the like terms to simplify it a little:
From there, add the 18 to both sides to cancel it out, which leaves you with:
Then just divide 198 by 9, and you'll get what X equals.
Hope it helps!

Question:
Use technology to approximate the solution(s) to the system of equations to the nearest tenth of a unit.
Select all that apply.
(3.6,0.6)
(-2.6,0.4)
(-3.6,0.6)
(2.6,0.4)
(4.5,-1.5)
Answer:
Option A : is the solution to the system of equations.
Option D: is the solution to the system of equations.
Explanation:
The two equations are and
To determine the solution of the system of equations using technology, let us plot the equations in the graphing calculator.
The solution of the system of equations is the intersection of the two lines.
Thus, from the graph, we can see that the two lines f(x) and g(x) intersect at the points and
Rounding off the solution to the nearest tenth, we get,
and
Thus, the solution to the system of equations is and
Hence, Option A and Option D are the correct answers.
