Given:
AD is diameter of the circle, AB is the tangent, and measure of arc ADC is 228 degrees.
To find:
The
and
.
Solution:
AD is diameter of the circle. So, the measure of arc AD is 180 degrees.




The measure inscribed angle is half of the corresponding subtended arc.



AB is the tangent. So,
because radius is perpendicular on the tangent and the point of tangency.




Therefore,
and
.
Absolute value of -3 is three, and then it just regular -3 equals -3 so basically whenever you see at -3 in those brackets or any negative number it means absolute value which will always be it’s positive version That negative number

Answer: 
Step-by-step explanation:
Given the following Quadratic equation:

You can change its formed by Completing the square.
In order to do Complete the square, you can follow these steps:
1. You can identify that:

2. Then, you can find
. This is:

3. Now you must add
to both sides of the Quadratic equation in order to keep the balance. Then:

4. Finally, simplifying by actoring and adding the like terms, you get:
