PLEASE HELP ASAP !!!

You know that a straight line has an angle of 180 degrees; 

48+x+x=180 <-- since they are all on the same time
48+2x=180 
2x=180-48 
2x=132
x=132/2
x=66

Therefore, the x value is 66 degree. 

Hope I helped :)

Which table shows a no change linear relationship?
Phantasy [73]

Answer:

C

Step-by-step explanation:

Each of the tables is a linear relationship. Linear relationships increase or decrease steadily by adding or subtracting a constant. Table A increases by 5. Table B decreases by 2. Table C doesn't change. Table D increase by 4.

A "no change" means the y values never change. The constant is 0 and is a horizontal line. Table C is the solution.
