Since the radius is 12, the equation is
.. x^2 +y^2 = 144
Answer:
I believe the answer is 24
Answer: First option.
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:
Step-by-step explanation:
56 1/2 because i did the math
Answer:
f-1 (x) = 2x + 2
Step-by-step explanation:
f(x) = x/2 -1
y = x/2 -1
interchanging the position of x and y
x= (y-2)/2
2x =y - 2
y = 2x + 2
f^-1 (x) = 2x + 2
