Step-by-step explanation:
You can idenfity in the figure that
is formed by two secants that intersect outside of the given circle.
It is important to remember that, by definition:

Knowing this, you can set up the following equation:

Therefore, you must substitute values into the equation and then evaluate, in order to find the measure of the angle
.
This is:

Answer:
y-intercept is 30
Step-by-step explanation:
Given the model
comparing this model to the equation of a straight lines we can get the y- intercept

The y- intercept is 30 which is the constant factor and it describes to us about the one-time registration fee of $30.
