The answer is not A or B

Answer:
C) 4
Step-by-step explanation:
Arcs on one side of the diameter adds upto 180°.
Therefore,
[tex](2 + 17x) \degree + 54 \degree + 56 \degree = 180 \degree \\ \\ (2 + 17x) \degree + 110 \degree = 180 \degree \\ \\ (2+ 17x) \degree = 180 \degree - 110 \degree\\ \\ (2 + 17x) \degree = 70 \degree \\ \\ 2 + 17x = 70 \\ 17x = 70 - 2 \\ \\ x = \frac{68}{17} \\ \\ x = 4[/tex]
Answer:
Choice C) 4
Step-by-step explanation:
You can do this in multiple different ways but I will do it in the way I believe will be the fastest.
So since we already know everything on one side of the line, we can use that to find x. The line is 180° and since the angles are on the line we know that they will all add up to 180.
For this we will need an equation:
[tex]2+17x+54+56=180[/tex]
Now we add the like terms:
[tex]112+17x=180[/tex]
Subtract the 112 on both sides:
[tex]17x=68[/tex]
Divide the 17 on both sides:
[tex]x=4[/tex]
