Answer:
C. 105° = (5x - 70)°
Step-by-step explanation:
Vertically opposite angles are equal in size.
105° = (5x - 70)°
The correct answer is choice C.
So, these are actually pretty simple once you learn the equality used to solve for "x" and when to implement this method. You can use this equality to solve for a segment "x" anytime that two secant lines cutting through a circle come from the same point outside the circle.
Secant: by geometric definition is just a straight line that cuts a curve into multiple pieces.
I did one of them for you hopefully you can use my work for "a" to help you solve for "b".
For a. I got x=7.
