Answer:
X=27
Step-by-step explanation:
90+36=126
180-126=54
54/2=27
The line is strait therefore it is 180 degrees and the right angle is 90 plus the 36 angle equals 126. Then you take that away from 180 to find how much the other angle is. After you find that it is 54 you divide it by 2 because it is 2x.

Answer:
C) The solution for the system of equations
Step-by-step explanation:
Point (3, 120) is where both lines intercept!
Basically, (3, 120) is where both equations are equal to each other.
(120 = 20(3) + 60) = (120 = 40(3))
We can test it!
120 = 20(3) + 60
120 = 60 + 60
120 (Correct)
120 = 40(3)
120 = 120 (Correct)
