Answer:
60°
Step-by-step explanation:
2x and x are linear pair,
=> 2x + x = 180
=> 3x = 180
=> x = 180/3
=> x = 60°
=>2x =120°
The answer is 20
Your welcome
Answer: its option 3 I just did the test right now
Step-by-step explanation:
For this case, the first thing you must do is to graph both functions in the same Cartesian plane.
Then, to find the solution you should see where both functions are cut.
For this case, looking at the graph, we see that the solution of the system of equations is
x = -2
y = 3
answer (x, y) = (- 2, 3)
