Answer:
160
Step-by-step explanation:
The measure of an arc is always twice the degree of the corresponding angle inside the circle. For example, the measure of arc DC is just double the measure of angle DOC; angle DOC is 44 degrees, so arc DC must be 88 degrees.
Angle COB is 80 degrees, so arc CB is 160 degrees.
Answer:
The two roots of the quadratic equation are

Step-by-step explanation:
Original quadratic equation is 
Divide both sides by 9:

Add
to both sides to get rid of the constant on the LHS
==> 
Add
to both sides

This simplifies to

Noting that (a + b)² = a² + 2ab + b²
If we set a = x and b =
we can see that
= 
So

Taking square roots on both sides

So the two roots or solutions of the equation are
and 

So the two roots are

and
